Hydrosulfonylation of Unactivated Alkenes and Alkynes by Halogen-Atom Transfer (XAT) Cleavage of S<sup>VI</sup>–F Bond
Wu Xing, Bing Gao
Abstract
A photochemical halogen-atom transfer (XAT) method for generating sulfonyl radicals from aryl sulfonyl fluorides has been developed. It allows the hydrosulfonylation of unactivated alkenes, which was challenging to achieve through our previous single-electron transfer route. This reaction has excellent functional group tolerance and substrate scope under mild conditions.
