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 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.
