Cu-catalyzed efficient construction of S (Se)-containing functional organosilicon compounds

Abstract

A Cu-catalyzed cascade reaction of four-membered silacyclobutanes (SCBs) and thiosulfonates to construct S (Se)-containing organosilicon compounds was developed. The protocol shows a wide range of substrate scope, high functional group compatibility and mild reaction conditions. New C–S (Se) and Si–O bonds were constructed in one step.
