Formation of silanethiols by reaction of silanes with carbonyl sulfide: Implications for radical-chain reduction of thiocarbonyl compounds by silanes

Carbonyl sulfide reacts with organosilanes at 60-85°C, in the presence of a radical initiator, to give the corresponding silanethiols. Triphenylsilane is confirmed as an excellent replacement for tributyltin hydride in the Barton-McCombie deoxygenation of alcohols via thier xanthates under mild conditions. Reduction of xanthates by silanes can produce COS as a by-product, leading to the in situ formation of silanethiol that will then act as a protic polarity-reversal catalyst for the reduction.
