The liquid hydrogen chloride solvent system. Part IX. Oxidation of some phosphorus(III) compounds

Abstract

The reactions of the halogens and related compounds with phosphorus(III) compounds in liquid hydrogen chloride have been investigated. Where oxidation occurred phosphorus was oxidised from the + 3 to the +5 oxidation state. The reactions were followed conductimetrically wherever possible. Evidence was obtained for the existence of the ions PCl₃Br⁺ and Ph₃PCl⁺ by stabilising them as the tetrachloroborate salts.
