Iridium-catalyzed dehydrogenative dimerization of benzylmethylsilanes via silylation of C(sp3)H bonds adjacent to a silicon atom

Abstract

Dehydrogenative dimerization of benzylmethylsilanes under iridium catalysis via site-selective sequential silylations of a C(sp3)H bond of the methyl group and ortho C(sp2)H bond of the benzyl group is described. Silicon-containing heterocycles were obtained in a single step from readily available functionalized benzylmethylsilanes.
