Abstract

AbstractA catalyst‐free strategy has been established for the synthesis of β‐oxo sulfones via visible light‐induced oxysulfonylation of alkenes with arylazo sulfones with dioxygen in air. The present photoinduced transformation proceeds smoothly at room temperature in the absence of an external photosensitizer, which not only provides a mild and efficient approach to various β‐oxo sulfones, but also opens a different reaction mode for the photochemical reaction of arylazo sulfones.magnified image
