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。
