摘要

Alkyl radicals, obtained by reaction of Bu3Sn'or ClHg'with alkylmercury halides, will undergo regioselective and in some cases stereospecific substitution by a free radical chain addition- elimination mechanism with 1-alkenylstannanes or-mercurials. The chain reaction is also observed for 1-alkynyl derivatives and in the photostimulated demercuration of mixed alkyl and 1-alkenyl-or 1-alkynylmercurials. Chain propagation with alkyl radical formation is ...
