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.
