Only a few methods have been described for the preparation of hypophosphite esters (alkyl phosphinates, ROP(O)H2). As a result, comparatively few applications have been reported, and these intermediates have not been widely exploited in organophosphorus chemistry despite their synthetic potential. Herein, we describe a very general, practical, and high-yielding synthesis of hypophosphite esters, based
仅描述了几种制备次磷酸酯的方法(次膦酸烷基酯,ROP(O)H 2)。结果,已经报道了相对较少的应用,尽管这些中间体具有合成潜力,但尚未在有机磷化学中得到广泛利用。在此,我们基于次磷酸及其某些盐与烷氧基硅烷的反应,描述了一种非常通用,实用且高产的次磷酸酯合成方法。该方法学解决了与先前报道的反应有关的许多问题。我们的酯化反应是在各种溶剂中于中等温度下进行的,在这些条件下,酯具有明显的热稳定性。此外,所使用的试剂是廉价的,并且不必是严格无水的。讨论了该方法的范围和局限性,
