The facts influencing the high stereoselectivity were discussed. It is proposed that the stability of the tri- molecular transition state or the stereoelectronic effect of the vinyl anion intermediate formed by the nucleophilic addition of halide anion to the electron-deficient carbon- carbon triple bond might be responsible for the high Z-stereoselectivity.

通过对影响反应的高立体选择性因素的研究，认为反应的三分子过渡态的稳定性或生成的烯基负离子中间体的立体电子效应决定了反应的高度Z立体选择性。
