Synthesis of [1,3]-thiasilolanes via rare-earth-catalysed intramolecular α-C(sp3)-H silylation of alkyl sulphides with hydrosilanes

Abstract

The intramolecular α-C(sp3)-H silylation of alkyl sulfides with hydrosilanes has been achieved for the first time by the use of halfsandwich rare-earth catalysts. This transformation smoothly proceeds without the need for a H2 acceptor, offering an efficient and selective protocol for the synthesis of a new family of heterocyclic [1,3]-thiasilolanes.
