摘要

Recently, we presented the first results on the radical hydrosilylation using silylated cyclohexadienes of type 1. 5 The bisvinylic methylene group acts as the hydrogen donor in these chain reactions. 6,7 Thus, H-transfer leads to a cyclohexadienyl radical 2, which subsequently rearomatizes to provide the tert-butyldimethylsilyl radical and arene 3 (Scheme 1). Silyl radical addition onto the alkene leads to a β-silylalkyl radical, which upon reduction with 1 eventually affords ...
