A copper-catalyzed aerobic oxidative cross-coupling reactions for the synthesis of β-ketosulfones via formation of a C[sbnd]S bond has been demonstrated. Promoted by the crucial copper catalyst, perfect selectivity and good to excellent yields could be achieved. This method, including inexpensive copper catalyst, wide functional group tolerance, and open air conditions, make it very attractive and practical. More importantly, it also provides a versatile tool for the construction of β-ketosulfones from basic starting materials under mild conditions.

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.
