Abstract

A new efficient method to obtain various alkynylphosphanes R n P(-≡-R') 3 - n [R = Ar, Alk, alkoxy, amido R' = Ar, Het, Alk, CH 2 Z (Z = OMe, NMe 2 ), n = 0-2] has been developed by means of cross-coupling reaction of chlorophosphanes R n PCl 3 - n (R = Ar, Alk, Alkoxy) with terminal alkynes catalyzed by cuprous salts.
