✦ Synopsis

The synthesis of di(a-thieny1)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 o f an adduct obtained by use of a radical trap. 0
