Abstract:
Both 2‐phenyl‐2‐furylhexamethyltrisilane ( 1 ) and 2‐phenyl‐2‐thienylhexamethyltrisilane ( 2 ) were synthesized by conventional organometallic reactions. The photolysis of 1 in the presence of 2,3‐dimethyl‐1,3‐butadiene led to normal silylene‐olefin addition and silylene CH insertion reactions. However, when 2 was photolyzed in a methanol‐cyclohexene system, an apparent radical reaction occurred. We suspect that the sulfur atom of the thienyl group strongly stabilizes a silyl radical. This result was supported by both identifying its typical radical reaction products and examining the ESR spectrum of its adduct with a radical trap.
