Abstract With the aim to explore metal‐ligand cooperation across Pd−S linkages, we designed a quinoline‐based PNS tridentate ligand and prepared Pd(II) complexes thereof. Optimal solubility stability of dicationic complex [(PNS)Pd(II)] 2 2+ IV were achieved with B(C 6 F 5 ) 4 – as counter‐anion. It adopts thiolate‐bridged dimeric structure (PdS) core, but readily activates hydrosilanes linkage. The resulting mononuclear hydride [(PNS SiR3 )Pd(II)H] + VI was characterized by multi‐nuclear NMR spectroscopy Si−H bond coordination/activation studied computationally. Complex found efficiently catalyze hydrosilylation alkynes, internal well terminal, good stereo regioselectivity.

New approaches to achieve facile and reversible dihydrogen activation are of importance for synthesis, catalysis, hydrogen storage. Here we show that low-coordinate magnesium oxide complexes [{(RDipnacnac)Mg}2(μ-O)] 1, with RDipnacnac = HC(RCNDip)2, Dip 2,6-iPr2C6H3, R Me (1a), Et (1b), iPr (1c), readily react under mild conditions afford mixed hydride-hydroxide [{(RDipnacnac)Mg}2(μ-H)(μ-OH)] 4. Dehydrogenation 4 is strongly dependent on remote ligand substitution can be achieved by simple vacuum-degassing 4c (R iPr) regain 1c. Donor addition also releases affords donor adducts complexes. Computational studies suggest the mechanism involves nucleophilic attack an lone pair at a weakly bound H2···Mg complex in SN2-like manner induces heterolytic cleavage yield MgOH MgH unit. Alternative synthetic routes into 4b from hydride have been investigated ability 1 or act as catalysts hydrogenation 1,1-diphenylethene (DPE) has tested.

Abstract Utilization of clean and low‐cost water as the reductant to enable hydrogenation alkenes is highly attractive in green chemistry. However, this research subject considerably challenging due sluggish kinetics oxidation half‐reaction. It also very difficult avoid undesired because that far easier occur than desired from thermodynamic standpoint. Herein, challenge overcome by applying a cooperative catalysis where HCl used cocatalyst accelerate Pt/g‐C 3 N 4 ‐catalyzed suppress alkene. This provides an example for using proton source photocatalytic alkenes. The present method exhibits broad substrate applicability, allows various arylethenes aliphatic undergo smoothly.
