通过对烯烃和炔烃的氢膦酰化加成反应合成膦化合物的方法一直被广泛研究. 主要总结了非活化炔类化合物的氢膦酰化反应的两种不同机理: 氧化加成-迁移插入-还原消除机理, 即Chalk-Harrod型机理, 以及质子转移-还原消除机理. 分别详细讨论了两种不同机理的具体步骤, 并论述了支持这些步骤的实验和计算证据. 此外, 列举了少量其他类型的机理以及密切相关的共轭烯烃的氢膦酰化反应机理.

The synthesis of phosphine compounds through the addition reaction of H-[P(O)] species to olefins and alkynes has been extensively studied. Two different mechanisms of the addition of H-[P(O)] species to non-activated alkyne are mainly summarized. One is the oxidative addition-migration insertion-reductive elimination mechanism, namely the Chalk-Harrod type mechanism, and the other is the proton transfer-reductive elimination mechanism. This review elaborates on the specific steps of each mechanism, and discusses experimental and computational evidence supporting these steps. Additionally, a few other types of mechanisms are briefly mentioned. The mechanism of H-[P(O)] reaction with relevant conjugated dienes was also involved when closely related.

Key words: hydrophosphorylation, mechanistic study, Chalk-Harrod type mechanism, proton transfer, ligand to ligand hydrogen transfer
