The first copper-catalyzed tert-butyl sulfonylation reaction of alkynes with t-butylsulfinamide for the construction of (E)-vinyl sulfones has been developed. The cleavage of the N-S bond of t-butylsulfinamide, which was catalyzed by CuSO4·5Hs

2-Aryl-1-sulfonyl-substituted cyclobutanes were prepared in an intermolecular [2 + 2] photocycloaddition from various α,β-unsaturated sulfones and olefins upon irradiation at λ = 300 nm (26 examples, 60-99% yield). Lewis acids catalyzed the [2 + 2] photocycloaddition of 2-benzimidazolyl styryl sulfones. At short wavelengths, the latter substrates underwent C-S bond cleavage but AlBr3 (5 mol %) allowed for an intermolecular reaction with 2,3-dimethyl-2-butene at longer wavelengths. A chiral-at-metal Lewis acid (2 mol %) facilitated an enantioselective reaction (up to 77% ee).

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 s
