本文通过对一系列碳阴离子磷酰化反应的研究,对此反应的应用范围和优缺点作出了较科学的评价。指出反应物结构是影响反应的根本因素,较少共轭的碳阴离子和磷酰氯反应有较好的结果。α-砜基碳阴离子、α-磷酰基碳阴离子和磷酰氯反应提供了合成α-砜基膦酸酯、αβ-不饱和砜,甲撑双膦酸酯(或氧化膦)和乙烯基膦酸酯(或氧化膦)
This article through a series of carbon anion phosphorylation reaction of the reaction of the application of the advantages and disadvantages made a more scientific evaluation. It is pointed out that the structure of the reactants is the fundamental factor affecting the reaction, and the less conjugate carbon anion and phosphoryl chloride reaction have better results. The reaction of an alpha-sulfonecarbocarboxylate, alpha-phosphorylcarbocarboxylate and phosphoryl chloride affords the synthesis of alpha-sulfone phosphonates, alpha beta-unsaturated sulfones, methylene bisphosphonates (or phosphine oxides) and vinyl phosphonic acids Ester (or phosphine oxide)
