Abstract
Organophosphorus ligands are an invaluable family of compounds that continue to underpin important roles in disciplines such as coordination chemistry and catalysis. Their success can routinely be traced back to facile tuneability thus enabling a high degree of control over, for example, electronic and steric properties. Diphosphines, phosphorus compounds bearing two separated PIII donor atoms, are also highly valued and impart their own unique features, for example excellent chelating properties upon metal complexation. In many classical ligands of this type, the backbone connectivity has been based on all carbon spacers only but there is growing interest in embedding other donor atoms such as additional nitrogen (–NH–, –NR–) sites. This review will collate some important examples of ligands in this field, illustrate their role as ligands in coordination chemistry and highlight some of their reactivities and applications. It will be shown that incorporation of a nitrogen-based group can impart unusual reactivities and important catalytic applications.

Abstract
![]()
N-Triphos derivatives
(NP3R, R = alkyl, aryl)
and asymmetric variants (NP2RXR′, R′ = alkyl, aryl, X = OH, NR2, NRR′) are
an underexplored class of tuneable, tripodal ligands in relation to
the coordination chemistry of Re and Tc for biomedical applications.
Mixed-ligand approaches are a flexible synthetic route to obtain Tc
complexes of differing core structures and physicochemical properties.
Reaction of the NP3Ph ligand with the Re(V)
oxo precursor [ReOCl3(PPh3)2] generated
the bidentate complex [ReOCl3(κ2-NP2PhOHAr)], which possesses an unusual
AA’BB’XX’ spin system with a characteristic second-order
NMR lineshape that is sensitive to the bi- or tridentate nature of
the coordinating diphosphine unit. The use of the asymmetric NP2PhOHAr ligand resulted in the formation
of both bidentate and tridentate products depending on the presence
of base. The tridentate Re(V) complex [ReOCl2(κ3-NP2PhOAr)] has provided
the basis of a new reactive “metal-fragment” for further
functionalization in [3 + 2] mixed-ligand complexes. The synthesis
of [3 + 2] complexes with catechol-based π-donors could also
be achieved under one-pot, single-step conditions from Re(V) oxo precursors.
Analogous complexes can also be synthesized from suitable 99Tc(V) precursors, and these complexes have been shown to exhibit
highly similar structural properties through spectroscopic and chromatographic
analysis. However, a tendency for the {MVO}3+ core to undergo hydrolysis to the {MVO2}+ core has been observed both in the case of M = Re and markedly
for M = 99Tc complexes. It is likely that controlling this
pathway will be critical to the generation of further stable Tc(V)
derivatives. An N-centered tripodal heterofunctionalized
phosphine ligand
was used to generate a reactive “metal-fragment” based
on the {MVO}3+ (M = Re, 99Tc) core
for the formation of mixed-ligand [3 + 2] complexes. Characteristic
lineshapes arising from an AA’BB’XX’ spin system
are diagnostic of bidentate vs tridentate coordination modes of the
ligand.

Molecules 2021; 26:molecules26226809.

Abstract
The solid-state behaviour of two series of isomeric, phenol-substituted, aminomethylphosphines, as the free ligands and bound to PtII, have been extensively studied using single crystal X-ray crystallography. In the first library, isomeric diphosphines of the type Ph2PCH2N(Ar)CH2PPh2 [1a–e; Ar = C6H3(Me)(OH)] and, in the second library, amide-functionalised, isomeric ligands Ph2PCH2N{CH2C(O)NH(Ar)}CH2PPh2 [2a–e; Ar = C6H3(Me)(OH)], were synthesised by reaction of Ph2PCH2OH and the appropriate amine in CH3OH, and isolated as colourless solids or oils in good yield. The non-methyl, substituted diphosphines Ph2PCH2N{CH2C(O)NH(Ar)}CH2PPh2 [2f, Ar = 3-C6H4(OH); 2g, Ar = 4-C6H4(OH)] and Ph2PCH2N(Ar)CH2PPh2 [3, Ar = 3-C6H4(OH)] were also prepared for comparative purposes. Reactions of 1a–e, 2a–g, or 3 with PtCl2(η4-cod) afforded the corresponding square-planar complexes 4a–e, 5a–g, and 6 in good to high isolated yields. All new compounds were characterised using a range of spectroscopic (1H, 31P{1H}, FT–IR) and analytical techniques. Single crystal X-ray structures have been determined for 1a, 1b∙CH3OH, 2f∙CH3OH, 2g, 3, 4b∙(CH3)2SO, 4c∙CHCl3, 4d∙½Et2O, 4e∙½CHCl3∙½CH3OH, 5a∙½Et2O, 5b, 5c∙¼H2O, 5d∙Et2O, and 6∙(CH3)2SO. The free phenolic group in 1b∙CH3OH, 2f∙CH3OH,2g, 4b∙(CH3)2SO, 5a∙½Et2O, 5c∙¼H2O, and 6∙(CH3)2SO exhibits various intra- or intermolecular O–H∙∙∙X (X = O, N, P, Cl) hydrogen contacts leading to different packing arrangements.

Abstract
α-Aminophosphine-type ligands are of interest as building blocks of transition metal complexes. This review focuses on the utilization of α-aminophosphines as monodentate and bidentate ligands in platinum, palladium and rhodium complexes. Besides the linear derivatives, the applications of cyclic α-aminophosphines as ligands are also summarized. Various aspects, such as synthesis, structure and applications, as well as the catalytic activity of these complexes are discussed.

Abstract
The diphosphine ligand, N,N'-bis(2-diphenylphosphinoethyl)isophthalamide, dpipa, contains two amide groups and can form cis or trans chelate complexes or cis,cis or trans,trans bridged complexes. The amide groups are likely to be involved in intramolecular or intermolecular hydrogen bonding. This combination of properties of the ligand dpipa leads to very unusual structural properties of its complexes, which often exist as mixtures of monomers and dimers in solution. In the complex [Au2(μ-dpipa)2]Cl2, the ligands adopt the trans,trans bridging mode, with linear gold(I) centers, and the amide groups hydrogen bond to the chloride anions. In [Pt2Cl4(μ-dpipa)2], the ligands adopt the cis,cis bridging mode, with square planar platinum(II) centers, and the amide groups form intermolecular hydrogen bonds to the chloride ligands to form a supramolecular one-dimensional polymer. Both the monomeric and dimeric complexes [PtMe2(dpipa)] and [Pt2Me4(μ-dpipa)2] have cis-PtMe2 units with cis chelating or cis,cis bridging dpipa ligands respectively; each forms a supramolecular dimer through hydrogen bonding between amide groups and each contains an unusual NH···Pt interaction. An attempted oxidative addition reaction with methyl iodide gave the complex [PtIMe(dpipa)], which contains trans chelating dpipa, while a reaction with bromine gave a disordered complex with approximate composition [Pt2Me3Br5(μ-dpipa)2], which contains trans,trans bridging dpipa ligands.

Abstract
The 1:1 reaction of [W(CO)4(2-picoline)2] (1) with Ph2PCtriple bondC-Ctriple bondCPPh2 (2) led to {[cis-W(CO)4]2(µ-Ph2PC4PPh2)2} (3), in which two bis(diphenylphosphino)butadiyne ligands bridge two tetracarbonyltungsten centres. Reaction of 1 with excess 2 led to [cis-W(CO)4(Ph2PC4PPh2-κ1-P)2] (4), in which two dangling bis-phosphines are coordinated to one metal centre, and reaction of 2 with two equivalents of 1 led to {[W(2-picoline)(CO)4]2(µ-Ph2PC4PPh2)} (5), in which one ligand bridges two tungsten centres. Combination of 4 and 5 led to the trimeric complex {[cis-W(CO)4]3(µ-Ph2PC4PPh2)3} (6), in which three tetracarbonyltungsten centres are bridged by three bisdiphenylphosphinobutadiyne ligands. The dimeric complex 3 showed no reactivity towards alkyne cycloaddition; however, the trimeric complex 6 undergoes cycloaddition at moderate temperatures to form {[W(CO)4]3[µ3-C12(Ph2P)6]} (8), which contains a cyclododecatrienetriyene ring. Comparison of structural data for the template complexes 3 and 6, as well that of previously described platinum template complexes, suggests that alkyne cycloaddition reactions are favoured by proximity of the alkynyl carbons α to phosphorus in adjacent ligands.Key words: coordination chemistry, diyne, cycloaddition, templated reaction, tungsten.
