Benzenesulfonyl radical can be generated from sodium benzenesulfinate in aq
ueous acetic acid or formic acid. A benzenesulfonyl radical induced radical
reaction of omega-allylsulfonylalkyl substituted aromatic and heteroaromat
ic derivatives is described. Alkyl radicals can be generated efficiently fr
om allylsulfones. This sulfonyl radical induced reaction provides a synthet
ically useful method for the synthesis of polycyclic aromatic and heteroaro
matic derivatives. (C) 1999 Elsevier Science Ltd. All rights reserved.
