Summary: An intriguing strategy for copper-catalyzed hydroxymethylation of alkynes with CO2 and hydrosilane was developed. This strategy allows for selective triggering of direct hydroxymethylation and reductive hydroxymethylation, yielding a series of allylic alcohols and homobenzylic alcohols with high levels of Z/E, regio- and enantioselectivity. Such selectivity is attributed to the differences in response of vinylcopper intermediate to proton and CO2.
