Abstract:Readily accessible N-sulfonylaminophthalimides were developed to be efficient sulfonyl radical precursors upon being treated with a base/oxidant under mild conditions. The method was applied to the oxysulfonylation of olefins, providing βketosulfones and isobenzofurans stereoselectively. On the basis of control experiments, density functional theory calculations, and the literature, a plausible radical mechanism was proposed. The findings offered a chance to develop novel radical precursors based on diversely … Show more
