Abstract

Diphosphines of the class RPhP (CH2), PPhR (n= 2-6) have been prepared from the reactions of the corresponding Ph2P (CH2), PPhz with alkali metal followed by alkylation. Ultrasound irradiation should be applied in the reductive cleavage stage so as to assure the purity of the final products.
