Gold(I) complexes with chloro(diaryl)silyl ligand. Stoichiometric reactions and catalysis for O-functionalization of organosilane

An Au(I) complex with a chloro(diphenyl)silyl ligand [Au(SiPh2Cl)(PCy3)] (1a) is obtained from the reaction of Ph2SiH2 with [AuCl(PCy3)]. (4-FC6H4)2SiH2, (4-MeC6H4)2SiH2, and Ph2GeH2 react with [AuCl(PCy3)] to form complexes with the chlorodiarylsilyl ligand, [Au(SiAr2Cl)(PCy3)] (1b: Ar = C6H4-4-F, 1c: Ar = C6H4-4-Me) and with the chloro(diphenyl)germyl ligand, [Au(GePh2Cl)(PCy3)] (2a), respectively. Complex 1a reacts with H2O to form Ph2SiH(OH) and (Ph2SiH)2O, whereas the reaction of EtOH with 1a yields Ph2SiH(OEt) exclusively. Complex 1a catalyzes the hydrolysis of Ph2SiH2 ([Au]:[H2SiPh2]:[H2O] = 0.05:1.0:10.0) at 60 °C to yield Ph2SiH(OH) and (Ph2SiH)2O. The reaction of Ph2SiH2 with HOEt in the presence of a catalytic amount of 1a affords Ph2SiH(OEt). Both stoichiometric and catalytic reactions using 1a lead to the recovery of [AuCl(PCy3)] from the reaction mixture.

Plasma-Assisted Synthesis of Monodispersed and Robust Ruthenium Ultrafine Nanocatalysts for Organosilane Oxidation and Oxygen Evolution Reactions

We report a facile and general approach for preparing ultrafine ruthenium nanocatalysts by using a plasma-assisted synthesis at 2 supports. This gives robust catalysts with excellent activities in both organosilane oxidation and the oxygen evolution reaction.

Metal-free catalytic hydrogen production from a polymethylhydrosilane-water mixture

Hydrogen gas is the most promising carbon-free energy carrier although its on-demand generation remains a formidable challenge. One of the potential pathways for generating hydrogen is through hydrolytic oxidation of organosilanes. Here, we demonstrate that the hydroxide ion OH- serves as a potent room-temperature metal-free catalyst in the hydrolytic oxidation of polymethylhydrosilane, PMHS to hydrogen gas and the corresponding silanol with a turnover number and turnover frequency in excess of 200 and 8 min-1 respectively. Kinetic studies suggest the hydrogen generation rate is first order with respect to PMHS and OH- but zero order with respect to water. The first step of the reaction, where the Si center of PMHS is attacked by the OH- ion, is believed to be the rate-determining step.
