General access to a novel class of silyl heterocycles

2-Trimethylsilyl-substituted five-membered heterocycles can be accessed through the reaction of bromo(methoxy)methyltrimethylsilane with 1,2-dithiols, 1,2-mercapto alcohols, 1,2-mercapto amines, and 1,2-hydroxy amines, leading to the formation of several 2-silylated 1,3-dithiolanes,-oxathiolanes,-thiazolidines, and-oxazolidines.
