Abstract
AbstractOxidative coupling methodology is widely applied for the formation of carbon‐carbon and carbon‐heteroatom bonds. This review focuses on methods for oxidative sulfonylation of multiple bonds involving sulfonyl hydrazides, sulfinic acids and their salts as sulfonylation reagents. Under oxidative conditions, they generate sulfonyl radicals, trapped by multiple carbon‐carbon bonds resulting in a variety of SO2‐containing products: mainly, vinyl and alkynyl sulfones, hydroxy‐, keto, and halo‐substituted sulfones, sulfonylated derivatives of carbo‐ and heterocycles. This exhaustive review summarizes 321 references from 1996 to 2020 with the specialization of the studies of the last five years, and is divided into the chapters according to the classes of compounds being sulfonylated.magnified image
