Abstract

Abstract A process for the conversion of hypophosphorous acid (H 3 PO 2, HPA) and alcohols into various H-phosphonate diesters [(RO) 2 P (O) H] is described. The new reaction provides a missing bridge between HPA and important H-phosphonates, completely avoiding the use of PCl 3. Nickel chloride or nickel on silica catalyze the oxidative phosphorylation of alkyl phosphinates with various alcohols or water. The ...
