The practical synthesis of P-stereogenic tertiary phosphines, which have wide applications in asymmetric catalysis, materials, and pharmaceutical chemistry, represents a significant challenge. A regio- and enantioselective hydrophosphination using cheap and ubiquitous alkynes catalyzed by a nickel complex was designed, in which the toxic and air-sensitive secondary phosphines were prepared in situ
P-立体叔膦的实际合成在不对称催化、材料和药物化学中具有广泛的应用,是一项重大挑战。设计了一种由镍配合物催化的廉价和普遍存在的炔烃的区域和对映选择性氢膦化反应,其中原位制备了有毒和空气敏感的二级膦来自工作台稳定的二级氧化膦。这种方法已被证明具有前所未有的底物范围和官能团兼容性,可提供电子和结构多样化的 P(III) 化合物。这些产物可以很容易地转化为双齿配体和有机催化剂的各种前体,以及各种包含P和金属立体中心的过渡金属配合物。
