The effects of aryl ring substitution on the dynamic resolution of aryl(methyl)phenylphosphanes under asymmetric Appel reaction conditions have been studied. As expected, substitution at the ortho position strongly affects the degree ofstereoselection that can be achieved. Unexpectedly, however, there was no variation of stereoselectivity with the electronic nature of the para substituents, which suggests
研究了在不对称 Appel 反应条件下芳环取代对芳基(甲基)苯基膦动态拆分的影响。正如预期的那样,邻位取代强烈影响可以实现的立体选择的程度。然而,出乎意料的是,立体选择性没有随对位取代基的电子性质而变化,这表明存在两个选择过程。在通往所需叔膦底物的路线上,在芳基苯基氯化膦中观察到了一个不寻常的卤素交换过程。
