Silver-mediated aminophosphinoylation of propargyl alcohols with aromatic amines and H-phosphine oxides leading to α-aminophosphine oxides

Abstract

A new silver mediated aminophosphinoylation of propargyl alcohols with aromatic amines and H-phosphine oxides for the construction of α-aminophosphine oxides has been developed. The CN and CP bond could be efficiently formed in one pot operation via sequential CC and CO bond cleavage of propargylic alcohols. This present methodology, which not only provides a simple and alternative strategy for the synthesis of α-aminophosphine oxides, but also opens a new window for the cleavage reactions of propargyl alcohols via dealkynalation coupling.
