Abstract
Caged complexes can provide impressive selective catalysts. Due to the complex shapes of such caged catalysts, however, the level of selectivity control of a single substrate cannot be extrapolated to other substrates. Herein, the substrate scope using 41 terminal alkene substrates is investigated in the hydroformylation reaction with an encapsulated rhodium catalyst [Rh(H)(CO)3(P(mPy3(ZnTPP)3))] (CAT1). For all substrates, the amount of branched products formed was higher with CAT1 than with the unencapsulated reference catalyst [Rh(H)(CO)2(P(mPy3))2] (CAT2) (linear/branched ratio between 2.14 and 0.12 for CAT1 and linear/branched ratio between 6.22 and 0.59 for CAT2). Interestingly, the level of cage induced selectivity depends strongly on the substrate structure that is converted. Analysis of the substrate scope combined with DFT calculations suggests that noncovalent interactions between the substrate moieties and cage walls play a key role in controlling the regioselectivity. Consequently, these supramolecular interactions were further optimized by replacing the ZnTPP building block with a zinc porphyrin analog that contained OiPr substituents on the meta position of the aryl rings. The resulting caged catalyst, CAT4, converted substrates with even higher branched selectivity.

Abstract
Transition metal catalysis benefitting from supramolecular interactions in the secondary coordination sphere in order to pre-organize substrates around the active site and reach a specific selectivity typically occurs under long reaction times and mild reaction temperatures with the aim to maximize such subtle effects. Herein, we demonstrate that the kinetically labile Zn⋯N interaction between a pyridine substrate and a zinc-porphyrin site serving for substrate binding is a unique type of weak interaction that enables identification of supramolecular effects in transition metal catalysis after one hour at a high reaction temperature of 130 °C. Under carefully selected reaction conditions, supramolecularly-regulated palladium-catalyzed Mizoroki-Heck reactions between 3-bromopyridine and terminal olefins (acrylates or styrenes) proceeded in a more efficient manner compared to the non-supramolecular version. The supramolecular catalysis developed here also displayed interesting substrate-selectivity patterns.

Abstract
![]()
The use of antimony
and bismuth in supramolecular chemistry has
been largely overlooked in comparison to the lighter elements of Group
15, and the coordination chemistry of the tripodal ligands [Sb(3-py)3] and [Bi(3-py)3] (L) containing the heaviest p-block
element bridgehead atoms has been unexplored. We show that these ligands
form a common hybrid metal–organic framework (MOF) structure
with Cu(I) and Ag(I) (M) salts of weakly coordinating anions (PF6–, SbF6–, and
OTf–), composed of a cationic substructure of rhombic
cage (M)4(L)4 units linked by Sb/Bi–M
bonding. The greater Lewis acidity of Bi compared to Sb can, however,
allows anion···Bi interactions to overcome Bi–metal
bonding in the case of BF4–, leading
to collapse of the MOF structure (which is also seen where harder
metals like Li+ are employed). This study therefore provides
insight into the way in which the electronic effects of the bridgehead
atom in these ligand systems can impact their supramolecular chemistry. The Lewis acidity of the Group 15 bridgehead
atoms (E =
Sb vs Bi) proves to be a decisive structural directing factor in the
coordination of tris(3-pyridyl) ligands E(3-py)3, being
responsible for promoting or disfavoring E−metal or E···anion
interactions.

Abstract
Supramolecular main group chemistry is a developing field which parallels the conventional domain of metallo-organic chemistry. Little explored building blocks in this area are main group metal-based ligands which have the appropriate donor symmetry to build desired molecular or extended arrangements. Tris(pyridyl) main group ligands (E(py)3 , E=main group metal) are potentially highly versatile building blocks since shifting the N-donor arms from the 2- to the 3-positions and 4-positions provides a very simple way of changing the ligand character from mononuclear/chelating to multidentate/metal-bridging. Here, the coordination behaviour of the first main group metal tris(4-pyridyl) ligands, E(4-py)3 (E=Sb, Bi, Ph-Sn) is explored, as well as their ability to build metal-organic frameworks (MOFs). The complicated topology of these MOFs shows a marked influence on the counter anion and on the ability of the E(4-py)3 ligands to switch coordination mode, depending on the steric and donor character of the bridgehead. This structure-directing influence of the bridgehead provides a potential building strategy for future molecular and MOF design in this area.

Abstract
The use of secondary interactions between substrates and catalysts is a promising strategy to discover selective transition metal catalysts for atom-economy C-H bond functionalization. The most powerful catalysts are found via trial-and-error screening due to the low association constants between the substrate and the catalyst in which small stereo-electronic modifications within them can lead to very different reactivities. To circumvent these limitations and to increase the level of reactivity prediction in these important reactions, we report herein a supramolecular catalyst harnessing Zn⋅⋅⋅N interactions that binds to pyridine-like substrates as tight as it can be found in some enzymes. The distance and spatial geometry between the active site and the substrate binding site is ideal to target unprecedented meta-selective iridium-catalyzed C-H bond borylations with enzymatic Michaelis-Menten kinetics, besides unique substrate selectivity and dormant reactivity patterns.

Abstract
![]()
Binding of molecules in molecular cages based on self-assembled
concave building blocks has been of great interest to scientists for
decades. The binding of static molecular fragments inside cage-like
molecular structures is generally based on complementarity of host
and guest in terms of shape and interactions. The encapsulation of
homogeneous catalysts in molecular cages is of interest as activity,
selectivity, and stability can be controlled by the cage as second
coordination sphere, reminiscent of how enzymes control chemical reactivity.
Homogeneous catalysts, however, are not static guest molecules as
catalysts change in shape, charge, and polarity during the catalytic
cycle, representing the challenges involved in cage controlled catalysis.
To address these issues, we developed a new strategy that we coined
the “ligand template approach for catalyst encapsulation”.
This strategy relies on ligand building blocks that contain multiple
orthogonal binding sites: the central ligand (mostly phosphorus) is
bound to the transition metal required for catalysis, while other
binding sites are used to construct a cage structure around the transition
metal atom through self-assembly. By design, the catalyst is inside
the capsule during the catalytic cycle, as the central ligand is coordinated
to the catalyst. As the approach is based on a self-assembly process
of building blocks, the catalyst properties can be easily modulated
by modification of building blocks involved. In this Account,
we elaborate on template ligand strategies for
single catalyst encapsulation, based on divergent ligand templates
and the extension to nanospheres with multiple metal complexes, which
are formed by assembly of convergent ligand templates. Using the mononuclear
approach, a variety of encapsulated catalysts can be generated, which
have led to highly (enantio)selective hydroformylation reactions for
encapsulated rhodium atoms. Besides the successes of encapsulated
rhodium catalysts in hydroformylation, mononuclear ligand template
capsules have been applied in asymmetric hydrogenation, the Heck reaction,
copolymerization, gold catalyzed cyclization reactions, and hydrosilylation
reactions. By changing the capsule building blocks the electronic
and steric properties around the transition metal atom have successfully
been modified, which translates to changes in catalyst properties.
Using the convergent ligand templates, nanospheres have been generated
with up to 24 complexes inside the sphere, leading to very high local
concentrations of the transition metal. The effect of local concentrations
was explored in gold catalyzed cyclization reactions and ruthenium
catalyzed water oxidation, and for both reactions, spectacular reaction
rate enhancements have been observed. This Account shows that the
template ligand approach to provide catalyst in well-defined specific
environments is very versatile and leads to catalyst properties that
are not achievable with traditional approaches.

Abstract
The hydroformylation reaction is one of the most intensively explored reactions in the field of homogeneous transition metal catalysis, and many industrial applications are known. However, this atom economical reaction has not been used to its full potential, as many selectivity issues have not been solved. Traditionally, the selectivity is controlled by the ligand that is coordinated to the active metal center. Recently, supramolecular strategies have been demonstrated to provide powerful complementary tools to control activity and selectivity in hydroformylation reactions. In this review, we will highlight these supramolecular strategies. We have organized this paper in sections in which we describe the use of supramolecular bidentate ligands, substrate preorganization by interactions between the substrate and functional groups of the ligands, and hydroformylation catalysis in molecular cages.

Abstract
Finding new catalysts for the release of molecular hydrogen from methanol is of high relevance in the context of the development of sustainable energy carriers. Herein, we report that the ruthenium complex Ru(salbinapht)(CO)(Pi‐Pr3) {salbinapht=2‐[({2′‐[(2‐hydroxybenzyl)amino]‐[1,1′‐binaphthalen]‐2‐yl}imino)methyl]phenolato} (2) catalyzes the methanol dehydrogenation reaction in the presence of base and water to yield H2, formate, and carbonate. Dihydrogen is the only gas detected and a turnover frequency up to 55 h−1 at 82 °C is reached. Complex 2 bears a carbonyl ligand that is derived from methanol, as is demonstrated by labeling experiments. The carbonyl ligand can be treated with base to form formate (HCOO−) and hydrogen. The nature of the active species is further shown not to contain a CO ligand but likely still possesses a salen‐derived ligand. During catalysis, formation of Ru(CO)2(H)2(P‐iPr3)2 is occasionally observed, which is also an active methanol dehydrogenation catalyst.

Abstract
Transition metal catalysis plays an important role in both industry and in academia where selectivity, activity and stability are crucial parameters to control. Next to changing the structure of the ligand, introducing a confined space as a second coordination sphere around a metal catalyst has recently been shown to be a viable method to induce new selectivity and activity in transition metal catalysis. In this review we focus on supramolecular strategies to encapsulate transition metal complexes with the aim of controlling the selectivity via the second coordination sphere. As we will discuss, catalyst confinement can result in selective processes that are impossible or difficult to achieve by traditional methods. We will describe the template-ligand approach as well as the host-guest approach to arrive at such supramolecular systems and discuss how the performance of the catalyst is enhanced by confining it in a molecular container.

Abstract
Receptor 1, composed of two deoxycholic acid moieties appended to a Zn-salophen complex, was prepared, characterized and tested for anion binding by (1)H NMR and UV-vis spectroscopic techniques. While in polar DMSO, 1 is able to bind phosphate (K = ∼700 M(-1)), the addition of water severely diminishes the association. In a 1 : 9 water-DMSO mixture, the binding constant K is only ca. 20 M(-1). Notably, in an aqueous solution of CTABr micelles (CTABr 10 mM, cmc = ∼1 mM), the zinc-salophen conjugate 1, due to its two non-polar bile-acid moieties, becomes solubilized and, most importantly, it almost completely recovers its binding ability towards phosphate, displaying a remarkable affinity (K = ∼450 M(-1)) in water.

Abstract
In this study we introduce a series of monodentate pyridine-based ligands for which the phosphorus coordination mode to rhodium can be controlled by the binding of Zn(II)-templates to the pyridyl group. A series of monodentate phosphoroamidite and phosphite ligands have been prepared and studied under hydroformylation conditions by in situ high-pressure NMR and IR techniques. These studies reveal the exclusive formation of rhodium hydride complexes in which the phosphorus atom of the ligand resides in an axial position, trans to the hydride, but only after addition of Zn(II)-template. In the absence of these templates the usual mono-coordinated rhodium hydrido complexes are formed, with the phosphorus ligated in the equatorial plane, cis to the hydride. The catalytic performance of these complexes is evaluated in asymmetric hydroformylation of unfunctionalised internal alkenes in which the supramolecular change is reflected in higher activity and selectivity.

Abstract
Self-assembly and characterization of novel heterodimeric diphosphine capsules formed by multiple ionic interactions and composed of one tetracationic diphosphine ligand and one complementary tetraanionic calix[4]arene are described. Encapsulation of a palladium atom within a diphosphine capsule is achieved successfully by using the metal complex of the tetracationic diphosphine ligand for the assembly process. In this templated approach to metal encapsulation, the transition-metal complex is an integrated part of the capsule with the transition metal located inside the capsule and is not involved in the assembly process. We present two approaches for capsule assembly by mixing solutions of the precharged building blocks in methanol and mixing solutions of the neutral building blocks in methanol. The scope of the diphosphine capsules and the metallodiphosphine capsules is easily extended by applying tetracationic diphosphine ligands with different backbones (ethylene, diphenyl ether, and xanthene) and cationic binding motifs (p-C(6)H(4)-CH(2)-ammonium, m-C(6)H(4)-ammonium, and m-C(6)H(4)-guanidinium). These tetracationic building blocks with different flexibilities and shapes readily associate into capsules with the proper capsular structure, as is indicated by (1)H NMR spectroscopy, 1D NOESY, ESI-MS, and modeling studies.

Abstract
Self-assembly and characterization of heterodimeric diphosphine capsules formed by multiple ionic interactions are described. The first type of capsules is composed of one novel tetrasulfonato-xantphos ligand and one complementary tetraammonium calix[4]arene. Encapsulation of a transition metal is achieved by self-assembly of a rhodium complex containing the tetraanionic diphosphine ligand and a tetracationic calix[4]arene. The second type of capsules is composed of two oppositely charged diphosphine ligands: one tetrasulfonato-xantphos and one tetraammonium-diphosphine (of the xantphos-, DPEphos-, and 1,2-bis(diphenylphosphino)ethane (dppe)-type). Bis(metallo) capsules, that is, simultaneous encapsulation of two different transition metals, are created by self-assembly of a palladium or platinum complex containing a tetracationic ligand and a rhodium complex containing a tetraanionic ligand. Diphosphine ligands with different flexibilities and shapes assemble into metallocapsules with a proper capsular structure, as is indicated by (1)H NMR and 1D-NOESY spectroscopy, ESIMS, and modeling studies.

Abstract
Recognition of inorganic phosphates PO(4)(3-), P(2)O(7)(4-), and P(3)O(10)(5-) and nucleotides AMP(2-), ADP(3-), and ATP(4-) by Zn(2+)-salophen complexes 1 and 2 in ethanol was investigated by different spectroscopic techniques. (31)P NMR and mass spectrometry showed that anions of both series are bound by 1 and 2, while absorption and emission studies revealed that only nucleotides produce relevant changes in the spectral properties of the two hosts. (1)H NMR studies proved that the adenine aromatic group is involved in the complexation, thus pointing out the role of supramolecular ditopic receptors played by salophen derivatives toward this class of biologically relevant substrates. The lifetime of the photogenerated triplet state of the Zn(2+)-salophen compounds was measured by nanosecond laser flash photolysis, and the observed changes upon increasing the concentration of nucleotides allowed the identification of the formation of a 1:0.5 host/guest intermediate complex additionally to the formation of a 1:1 complex.
