Studies on organosilicon reactive intermediates VIII synthesis and photochemistry of di(?-thienyl) hexamethyltrisilane

Abstract

The synthesis of di(α‐thienyl)hexamethyltrisilane (1) is described. In the photolysis of 1 with cyclohexene and methanol, an apparent radical reaction occurred. We suspect that the sulfur atom of the thienyl group strongly stabilizes an initially formed silyl radical. This idea was supported both by identifying typical radical reaction products and examining the ESR spectrum of an adduct obtained by use of a radical trap. © 1996 John Wiley & Sons, Inc.
