aryl(o‐tolyl)methanones with arylsulfonyl hydrazides or arylsulfonyl chlorides has been developed. Arylsulfonyl hydrazides and arylsulfonyl chlorides were employed as sulfonylating reagents respectively to complete this transformation. During the reaction, enols were generated in situ from aryl(o‐tolyl)methanones under UV irradiation, and subsequently reacted with sulfonyl radicals to provide a range of aryl(2

A novel multicomponent reaction of arynes, β-keto sulfones, and Michael-type acceptors is presented, providing an efficient method for the synthesis of polysubstituted naphthols and polysubstituted naphthalenes. Further investigation suggests that the tandemreaction may proceed via a sequential nucleophilic attack to arynes, intramolecular nucleophilic substitution followed by a Michael addition,
