Tri-n-butylphosphine-Catalyzed Phosphonoethylation Reactions of Hydrophosphoryl Compounds

Abstract

© 2019, Pleiades Publishing, Ltd. An efficient method for the synthesis of 1,2-bisphosphoryl compounds based on the addition of hydrophosphoryl derivatives to O,O-diethyl vinylphosphonate was developed. The reaction proceeds in mild conditions under catalysis with tri-n-butylphosphine and leads to the formation of the corresponding target products with high yield.
