Sulfonyl radicals generated from sulfonylhydrazides by the Bu4NI–tert-butyl hydroperoxide (TBHP) catalysis system underwent addition to a variety of α-methyl styrene derivatives give corresponding allylic sulfones. This selective sulfonylation is metal-free, operationally simple, and environmentally friendly.
