Abstract

Asymmetrically substituted bis(iminophosphoranes) derived from 1,2- bis(diphenylphosphino)ethane are prepared by Michael-type addition of easily available N,P,P-trisubstituted aminophosphanes to P-vinyl iminophosphoranes. Similarly P-alkylations of aminophosphanes with P-vinyl phosphane oxides and sulfides are also disclosed.
