This work describes an unprecedented methodology for the direct construction of invaluable Csp3−PIII bond through a nickel-catalyzed cross-coupling of Umpolung carbonyls with phosphine chlorides. A series of trivalent alkylphosphines were isolated and characterized as sulfides or borane complexes in moderate to good yields.
这项工作描述了一种前所未有的方法,用于通过 Umpolung 羰基与
氯化膦的
镍催化交叉偶联直接构建宝贵的 Csp 3 -P III键。分离出一系列三价烷基膦,并将其表征为
硫化物或
硼烷络合物,产率适中至良好。
