We herein report a visible-light photoredox-catalyzed regioselective sulfonylation of alkenes with sulfonyl hydrazides assisted by oximes at room temperature, which affords a variety of sulfones in good yields. The initial mechanistic experiments demonstrate that the hydroxyl group within oximes plays a crucial role in this sulfonylation.
