An environmentally friendly and efficient electrochemical fluorosulfonylation of styrenes has been developed. With the use of sulfonylhydrazides and triethylamine trihydrofluoride, a diverse array of β-fluorosulfones could be readily obtained. This reaction features mild conditions and a broad substrate scope, which could also be conveniently extended to a gram-scale preparation.
An atom-economic sulfonylation of unsaturated benzylic alcohols in water is described. In this transformation, dual roles of sulfonyl hydrazides serving as both sulfonyl source and reductant have been demonstrated, which enabled a facile and green method to synthesize alkyl sulfones from unsaturated benzylic alcohols. Moreover, this approach provides a practical access to deuterated alkanes from the

methyl sulfones via an unexpected C–S bond formation between sulfonylhydrazides and dimethylphosphite catalyzed by NaI under mild conditions has been established. This transformation provides an alternative and metal-free pathway to acquire various aryl methyl sulfones in good to excellent yields. Notably, dimethylphosphite was employed as a stable and readily available alkyl source.
已经建立了通过在温和条件下由 NaI 催化的磺酰肼和亚磷酸二甲酯之间意外形成 C-S 键形成芳基甲基砜的高度化学选择性途径。这种转化提供了一种替代的无金属途径,可以以良好到极好的收率获得各种芳基甲基砜。值得注意的是,亚磷酸二甲酯被用作稳定且容易获得的烷基源。
