  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

  酒精基米利斯-阿尔布佐夫反应：一种有效且环境友好的C–P（O）键形成方法

  摘要：

  著名的米利斯-阿尔布佐夫（Michaelis-Arbuzov）反应每年在实验室和工业中得到广泛使用，以生产数吨广泛使用的有机磷酰基化合物。但是，该方法和最近开发的改进的Michaelis-Arbuzov反应仍然存在一些局限性。现在，我们报告迈克尔斯-阿布佐夫（Michaelis-Arbuzov）反应的一种新的酒精转化形式，它可以提供一种有效且对环境有益的方法来解决已知的迈克尔斯-阿布佐夫（Michaelis-Arbuzov）反应的问题。即，使用正丁基4，各种各样的醇可以容易地与亚磷酸酯，亚膦酸酯和次膦酸酯反应，生成所有三种磷酰基化合物（膦酸酯，次膦酸酯和氧化膦）。NI催化的高效C–P（O）键形成反应。这种通用方法也可以轻松按比例放大，并在一锅中用于进一步的合成转化。

  Direct CH 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).

  Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkyl chlorides reacted with acylphosphine under relative mild and easily accessible condition, and differential phosphines were afforded in good yields.
