Scalable Synthesis of Hydrido-Disiloxanes from Silanes: A One-Pot Preparation of 1,3-Diphenyldisiloxane from Phenylsilane

A simple, one-pot, and high-yielding synthesis of 1,3-diphenyldisiloxane is presented. The preparation of similar symmetrical disiloxane materials is also accomplished with this same protocol. This mechano-chemical procedure is efficient and highly scalab

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.

Catalytic oxidation of diorganosilanes to 1,1,3,3-tetraorganodisiloxanes with gold nanoparticle assembly at the water-chloroform interface

The formation of the spherical self-assembly of gold nanoparticles (AuNPs) of 200 ± 20 nm size at the water-chloroform interface is achieved by employing the cyclotetrasiloxane [RSCH2CH2SiMeO]4 (R = CH2CH2OH) as the stabilizing ligand. The interfacially stabilized AuNPs act as a versatile catalyst for selective hydrolytic oxidation of only one of the Si-H bonds in secondary organosilanes, RR1SiH2 (R, R1 = alkyl, aryl, and sila-alkyl), to afford the high yield synthesis of 1,1,3,3-tetraorganodisiloxanes, (HRR1Si)2O. The study unravels for the first time the role of the photothermal effect arising from the excitation of the surface plasmon resonance of the AuNPs under visible light irradiation in enhancing the catalytic activity at ambient temperature.
