A mild and highly efficient reductive coupling of α-bromoketones with sulfonyl chlorides is described. Various β-ketosulfones can be obtained under mild conditions in good to excellent yields. This method provides a simple and practical access to β-ketosulfones and is amenable to gram scale with no special precautions to exclude air or moisture.

Key words: β-ketosulfones, α-bromoketones, sulfonyl chlorides, reductive coupling, manganese
