A novel temperature-dependent synthesis of organic sulfones from t-butylsulfinamide and alkenes under aerobic CuSO4-phosphorous acid catalyzed conditions was developed. Via this newly developed method, a series of vinyl sulfones and β-hydroxy sulfones were synthesized at 120 °C and 40 °C, respectively.
The first copper-catalyzed tert-butyl sulfonylation reaction of alkynes with t-butylsulfinamide for the construction of (E)-vinyl sulfones has been developed.
