An efficient one-pot sequence comprising a homolytic aromatic substitution followed by an ionic Horner−Wadsworth−Emmons olefination for the preparation of a small library of α,β-unsaturated oxindoles is presented. Microwave-induced heating is used to conduct these reactions. The homolytic aromatic substitution is mediated by the persistent radical effect.
