A new efficient method to obtain various alkynylphosphanes RnP(-R′)3-n [R = Ar, Alk, alkoxy, amido R′ = Ar, Het, Alk, CH2Z (Z = OMe, NMe2), n = 0-2] has been developed by means of cross-coupling reaction of chlorophosphanes RnPCl3-n (R = Ar, Alk, Alkoxy) with terminal alkynes catalyzed by cuprous salts.
