烯烃的氢膦化反应是有机合成中构建P—C键的核心策略. 发展了一种通过可见光催化烯烃的氢膦化合成叔膦化合物的新方法, 该反应显示出广泛的底物范围和优异的官能团相容性, 以中等至优异的收率(48%~95%)生成各种叔膦化合物. 提出了合理的反应机理: 光激发催化剂促使二苯基膦发生单电子氧化, 生成相应的膦自由基阳离子(PRC), 该中间体随即与烯烃的碳-碳双键发生自由基加成反应. 此外, 通过核磁共振(NMR)光谱成功监测到了季鏻盐和三价膦的生成, 为反应机理提供了直接佐证.

The hydrophosphination of olefins represents a fundamental strategy for the construction of P—C bonds in organic synthesis. A distinct protocol for the synthesis of tertiary phosphine compounds via visible light-catalyzed hydrophosphination of alkenes was developed. The reaction features a broad substrate scope and exceptional functional group compatibility, affording a diverse array of tertiary phosphine products with moderate to excellent yields ranging from 48% to 95%. A plausible reaction mechanism has been proposed. Specifically, photoexcited-catalyst-mediated single-electron oxidation of diphenyl- phosphine generates the corresponding phosphine radical cations (PRCs), which subsequently undergo radical addition across the carbon-carbon double bonds of alkenes. Furthermore, the formation of quaternary phosphonium salt and trivalent phosphine species was detected by 31P NMR spectroscopy, providing direct evidence for the reaction mechanism.
