Iodine‐Catalyzed One‐Pot Decarboxylative Sulfenylation of Electron‐Rich Arenes and Indoles

Abstract

Abstract Elemental iodine catalyzed decarboxylative sulfenylation (mono‐ or di) of electron‐rich alkoxybenzoic acids using benzenesulfonohydrazides as sulfenylating agent for the synthesis of diaryl sulfides under transition metal‐free conditions has been described. The method also works for the decarboxylative thioarylation (mono‐ or di) of indole carboxylic acids. Reactions showed very good functional group tolerance and excellent yields of sulfinylated products.
