An efficient and convenient strategy for the preparation of β-ketosulfone via C—H bond functionalization with sodium sulfite and aryl ethyl ketone/indenone under metal-free condition has been reported. The method has simple operation steps, mild reaction conditions and good functional group compatibility. The reaction enables the direct formation of C(sp3)—H into C—S bonds, thereby avoiding the use of strong oxidants and prefunctionalization of substrates. The β-ketosulfone compounds can be transformed as intermediates in organic synthesis.

Key words: sodium sulfintes, β-keto sulfones, C—H functionalization, C—S bond, transition metal-free
