Abstract

In the present work we report the unexpected formation of isomeric 3-benzoyl-2-phenylbenzo[b]furans using triphenylphosphonium salt and benzoyl chlorides under Wittig conditions. In particularly, we found that the o-[(benzoyloxy)benzyl]-triphenyl-phosphoranes constitute the key intermediate that reasonably undergoes benzoyl group migration.
