A simple and convenient visible-light-mediated method has been developed for the construction of β-ketosulfones via aerobic oxidative difunctionalization of alkynes with arylazo sulfones and dioxygen in air under photocatalyst-free conditions. The present photochemical methodology provides a facile and attractive protocol to construct a series of β-ketosulfones in moderate to good yields.

A 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.
