  Radical Phosphination of Organic Halides and Alkyl Imidazole-1-carbothioates

  摘要：

  Taking advantage of a radical-based methodology, mild and chemoselective phosphination reactions of organic halide and alkyl imidazole-1-carbothioates have been developed. The mild reaction conditions allow labile functional groups to survive during the reaction.

  Oxidation of Alkenes by Water with H₂ Liberation

  摘要：

  Oxidation by water with H-2 liberation is highly desirable, as it can serve as an environmentally friendly way for the oxidation of organic compounds. Herein, we report the oxidation of alkenes with water as the oxidant by using a catalyst combination of a dearomatized acridine-based PNP-Ru complex and indium(III) triflate. Compared to traditional Wacker-type oxidation, this transformation avoids the use of added chemical oxidants and liberates hydrogen gas as the only byproduct.

  differential phosphination reagents is reported. The acylphosphines show practicable reactivity with ArBr and ArOTf as the phosphination reagents, though they are inert to the air and moisture. The reaction affords trivalent phosphines directly in good yields with a broad substrate scope and functional group tolerance. This reaction discloses the acylphosphines’ capability as new phosphorus sources for the direct

  据报道，钯催化的 ArBr/ArOTf 的 C-P 键形成反应使用酰基膦作为差异膦化试剂。酰基膦显示出与作为膦化试剂的 ArBr 和 ArOTf 的实际反应性，尽管它们对空气和湿气呈惰性。该反应直接以良好的收率提供三价膦，具有广泛的底物范围和官能团耐受性。该反应揭示了酰基膦作为直接合成三价膦的新磷源的能力。
