synthesis of tervalent phosphorus esters, not yet mentioned in the literature, when potassium phosphate, as a unique base, is used in liquid–solid system. Symmetrical and unsymmetrical phosphites were obtained with good yields (65%–80%) using this method. The compounds were characterized by 31P NMR spectroscopy. © 2008 Wiley Periodicals, Inc.

三价磷酯的合成仍然是一个重要的关注领域,其中大部分再次针对金属催化反应的亚磷酸酯配体的合成。通常,它们是通过相应的氯化磷与适当的醇在胺存在下酯化而获得的。在本文中,我们提出了一种合成三价磷酯的新方法,当磷酸钾作为一种独特的碱用于液-固体系时,文献中尚未提及。使用这种方法可以以良好的收率 (65%–80%) 获得对称和不对称的亚磷酸酯。化合物通过31P NMR光谱表征。© 2008 Wiley Periodicals, Inc. 杂原子化学 19:360–364, 2008; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc。
