Abstract
Upon replacement of molybdenum by tungsten in DMSO reductase isolated from the Rhodobacteraceae family, the derived enzyme catalyzes DMSO reduction faster. To better understand this behavior, we synthesized two tungsten(VI) dioxido complexes [WVIO2L2] with pyridine- (PyS) and pyrimidine-2-thiolate (PymS) ligands, isostructural to analogous molybdenum complexes we reported recently. Higher oxygen atom transfer (OAT) catalytic activity was observed with [WO2(PyS)2] compared to the Mo species, independent of whether PMe3 or PPh3 was used as the oxygen acceptor. [WVIO2L2] complexes undergo reduction with an excess of PMe3, yielding the tungsten(IV) oxido species [WOL2(PMe3)2], while with PPh3, no reactions are observed. Although OAT reactions from DMSO to phosphines are known for tungsten complexes, [WOL2(PMe3)2] are the first fully characterized phosphine-stabilized intermediates. By following the reaction of these reduced species with excess DMSO via UV-vis spectroscopy, we observed that tungsten compounds directly react to WVIO2 complexes while the Mo analogues first form μ-oxo Mo(V) dimers [Mo2O3L4]. Density functional theory calculations confirm that the oxygen atom abstraction from WVIO2 is an endergonic process contrasting the respective reaction with molybdenum. Here, we suggest that depending on the sacrificial oxygen acceptor, the tungsten complex may participate in catalysis either via a redox reaction or as an electrophile.

Abstract
Direct peptide and protein activation is a challenging transformation because of the stabilizing effect of the amide group. While enzymes can be considered as prototypical systems that have evolved to achieve high selectivity and specificity, small-molecule catalysts that functionalize the amide group may accommodate a much larger selection of substrates but currently remain scarce. Here, by combining the desired features from both catalytic regimes we designed an artificial cyclodehydratase, a catalytic system for the site-selective modification of peptides and natural products by engrafting heterocycles into their scaffolds. The catalytic system features a molybdenum(VI) center that was decorated with a sterically congested tripod ligand. The optimized catalyst can introduce azolines into small molecules, natural products, and oligopeptides with high efficiency and minimal waste. We further demonstrate the utility of the new protocol in the direct functionalization of a single amide group in the presence of up to seven other chemically similar positions and in the direct conversion of these groups into amines and thioamides. This new mechanistic paradigm may address an unmet need for a general method for the selective and sustainable functionalization of peptides and natural products.

Abstract
The Adler-Becker reaction is a useful approach for the oxidative dearomatization of salicylic alcohols to spiroepoxydienones and has been applied in the total synthesis of several natural products. Despite the advantages, the substrate and product instability under the reaction conditions can decrease the reaction efficiency, leading to lower yields. Herein, we report the Adler-Becker reaction in a continuous flow for the transformation of reduced salicylaldehydes into spiroepoxydienones in a one-pot approach. For that, a heterogeneous oxidant based on periodate is developed, leading to an efficient continuous flow process, with higher productivity and shorter reaction times, when compared with batch conditions.

Abstract
A series of amine bisphenol (ABP) pro-ligands featuring amino acid ester pendant arms were prepared. Optimisation of the synthetic method allowed the facile incorporation of naturally occurring, chiral amino acids into the ABP scaffold with minimal racemisation. Reaction of the pro-ligands (LH2) with Pd(OAc)2, in the presence of amines, led to the formation of complexes with an unprecedented pincer-like O,N,O coordination mode around the PdII centre. The complexations in the presence of trialkylamines (NR3) afforded a mixture of LPdNR3 and LPdNHR2 species. The latter was shown to form via an ambient-temperature C-N cleavage involving unstable Pd(OAc)2(NHR2)2 intermediates. Using pyridine as base eliminated this dealkylation and resulted in the exclusive formation of LPd(py) complexes in high yields. In total, seven novel PdII ABP complexes were prepared, exhibiting distorted square-planar geometries with the asymmetric ligand moieties orientated towards the metal centre. The air- and moisture-stable LPd(py) complexes were successfully employed as catalysts in two types of C-C coupling reactions. The Suzuki-Miyaura coupling of 4'-bromoacetophenone and phenylboronic acid reached high yields (up to 81%), while a scope of further alkyl bromides was also efficiently converted using low catalyst loadings (1 mol%) and mild temperatures (40 °C). Furthermore, a Pd-pyridine complex achieved high activity in the Mizoroki-Heck coupling of styrene and 4'-bromoacetophenone.

Abstract
Interaction of [MoO2(acac)2] with internally functionalized oximes like HON=C(CH3)Ar (Ar = C4H3S, C4H3O or C5H4N) and Schiff's Bases derived from β – diketones like HOC(R)CHC(R′)=NC6H5 (R = R’ = CH3 or C6H5; R = CH3 and R’ = C6H5) led to the formation of yellow dioxomolybdenum(VI) complexes of the type [MoO2{ON=C(CH3)Ar}2] and [MoO2{OC(R)CHC(R′)=NC6H5}2]. Oximes were synthesized by green methodology. The newly synthesized complexes were characterized on basis of elemental analysis and various spectral findings. Anticandidal activity of [MoO2{ON=C(CH3)C6H4N}2] clearly reveals that the complex is biologically active against fungal diseases.

The structure of was confirmed by single crystal X-ray diffraction. These complexes were highly active initiators for the ring-opening polymerization of rac-lactide (rac-LA). The activity depended on the initiating group in the order of ≈ > . The activities of and during polymerization were controlled in situ with external redox reagents by reversibly switching the oxidation state of the iron center.

Abstract
A novel trimeric complex [{MoO2(L)}3] (L = tridentate aminoalcohol phenolate ligand) produces monomeric solvent adducts [MoO2(L)(solv)] in coordinating solvents. All complexes have been investigated as catalysts in oxotransfer reactions.

Abstract
The synthesis, excited-state dynamics, and applications of two series of air-stable luminescent tungsten(VI) complexes are described. These tungsten(VI) complexes show phosphorescence in the solid state and in solutions with emission quantum yields up to 22 % in thin film (5 % in mCP) at room temperature. Complex 2 c, containing a 5,7-diphenyl-8-hydroxyquinolinate ligand, displays prompt fluorescence (blue-green) and phosphorescence (red) of comparable intensity, which could be used for ratiometric luminescent sensing. Solution-processed organic light-emitting diodes (OLEDs) based on 1 d showed a stable yellow emission with an external quantum efficiency (EQE) and luminance up to 4.79 % and 1400 cd m-2 respectively. These tungsten(VI) complexes were also applied in light-induced aerobic oxidation reactions.

Abstract
The title compound, C34H54N2O2·0.25H2O, the organic molecule, a potential tetradentate ligand with a bulky phenolic donor, has overall mirror symmetry. A partially occupied water molecule of solvation is present in the lattice. The six-membered 1,3-diazinane ring displays a chair conformation. An intramolecular O—H⋯N hydrogen bond ocurs. In the crystal, molecules are linked by O—H⋯O interactions.
