The effects of aryl ringsubstitution 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
