    通过钠选择性裂解C-P键从ArCl制备有机膦的方法
    摘要:
    研究了磷化钠R 2 PNa和其他碱金属磷化物R 2 PM(M = Li和K)的制备,应用和反应机理。R 2 PNa可以通过SD(精细分散在矿物油中的钠)与次膦酸酯R 2 POR'和氯膦R 2 PC1的反应准确而选择性地制备。R 2 PNa也可以通过选择性裂解C–P键由三芳基膦和二芳基膦制备。在这些反应中,Na优于Li和K。R 2 PNa与多种ArCl反应以有效产生R 2PAr。ArCl优于ArBr和ArI,因为它们只会降低产品收率。另外,Ph 2 PNa优于Ph 2 PLi和Ph 2 PK,因为Ph 2 PLi不产生与PhCl的偶联产物,而Ph 2 PK仅产生低产率的产物。ArCl苯环上的吸电子基团极大地促进了与R 2 PNa的反应,而烷基降低了反应活性。氯乙烯和烷基氯RC1也有效地反应。当t-BuCl没有产生相应的产物,金刚烷基卤化物可以高产率得到相应的膦。通过这种方法,由相应的氯化物制备了多种膦。还可以方便地从Ph

    Direct CH amidation of arylphosphoryl compounds has been developed by using an IrIII catalyst system under mild conditions. A wide range of substrates could be employed with high functional‐group tolerance. This procedure was successfully applied for the first time to the asymmetric reaction giving rise to a P‐chirogenic center with a high diastereomeric ratio of up to 19:1 (90 % de).
