Generation of sulfonyl radicals from sulfonylhydrazides has been achieved in the presence of a non-toxic iron catalyst and oxygen. The intermolecular addition of resultant sulfonyl radicals to alkenes affords β-hydroxysulfone compounds.

Abstract An efficient organic electrosynthesis of tertiary β-hydroxysulfones from functionalized α-methylstyrenes with substitutedsodium sulfinates has been established. The novel electrosynthetic method provided the desired products in excellent yields, and the key structure was confirmed by X-ray single-crystal diffraction analysis.

attractive dioxygen activation by sulfinic acids was explored that is capable of performing efficiently without the assistance of transition metals or radical initiators. This reaction furnishes secondary and tertiary β‐hydroxysulfones under mild conditions; β‐hydroperoxysulfone was isolated as an important intermediate.
