• Evaluation and Development of Methodologies for the Synthesis of Thiophosphinic Acids
  作者：Karen R. Winters、Jean-Luc Montchamp

  DOI：10.1021/acs.joc.0c01151

  日期：2020.11.20

  thiophosphinic acids are reported. Ultimately, two major approaches were selected: (1) the Stec reaction of phosphorus amides with carbon disulfide; and (2) the one-pot synthesis of thiophosphorus acids from H-phosphinates, an organometallic nucleophile, and quenching with elemental sulfur. An application to the preparation of a potential chiral phosphorus organocatalyst is also reported.

  硫代磷酸R 1 R 2 P（S）OH构成一类重要的有机磷化合物，如果R 1 ≠R 2，则磷原子本质上是手性的。与旨在制备手性硫代磷酸的项目有关，考虑了各种可用的文献方法，但是很少有适合无味试剂的要求。在此，报道了我们关于硫代次膦酸合成的研究结果。最终，选择了两种主要方法：（1）磷酰胺与二硫化碳的Stec反应；（2）由H一锅合成硫代磷酸-次膦酸酯，一种有机金属亲核试剂，并用元素硫淬灭。还报道了在制备潜在的手性磷有机催化剂中的应用。
