ChemInform Abstract: Ambident Reactivity of Chlorophosphonium Compounds in Nucleophilic Reactions. Part 1. Reactions with Phosphorous Acid Esters.

Abstract The phosphonium salts (I) are coupled with phosphorous acid esters such as the phosphorochloridite (II) to give the phosphonous dichlorides (III) or the phosphonic dichlorides (V) depending on the polarity of the solvent used.
