Both 2-phenyl-2-furylhexamethyltrisilane (1) and 2phenyl-2-thienylhexamethyltrisilane (2) were synthesized by conventional organometallic reactions. The photolysis of 1 in the presence of 2,3-dimethyl-1,3butadiene led to normal silylene-olefin addition and silylene C-H insertion reactions. However,
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
