Chemoselective deoxygenation of ether-substituted alcohols and carbonyl compounds by B(C6F5)3-catalyzed reduction with (HMe2SiCH2)2

B(C6F5)3-catalyzed deoxygenation of ether-substituted alcohols and carbonyl compounds has been developed using (HMe2SiCH2)2 as the reductant. This unique reagent shows distinct superiority over traditional one silicon-centered hydrosilanes, giving the corresponding alkanes in high yields with good tolerance of ethers, aryl halides and alkenes. The control experiments suggest that (HMe2SiCH2)2 might facilitate the approach in an intramolecular Si/O activation manner.

Selective catalytic monoreduction of dichlorooligosilanes with Grignard reagents

Transition metal-catalyzed monoreduction of dichlorooligosilanes with Grignard reagents is reported. Among the examined catalysts, group 4 metal chlorides such as TiCl4 and Cp2TiCl2 gave the highest reactivity and good selectivity. The reducing power is effectively controlled by changing the catalysts and Grignard reagents to achieve sufficient selectivity depending on the oligosilane substrates.

Chloroplatinic acid catalyzed cyclization of silanes bearing pendant acetylenic groups

Chloroplatinic acid catalyzed, intramolecular hydrosilylation of acetylenes of structure HMe2SinSiMe2CCR (R = H or Ph, n = 2 or 3) proceeds via syn addition of the Si-H group to the carbon triple bond to give, predominantly, cyclic products having an
