Abstract

A number of triorganophosphorus dichloride compounds R3PCl2,(R3= substituted aryl, mixed aryl–alkyl or triaryl) have been synthesized from diethyl ether solution and characterised by analytical and 31P-{1H} NMR data in CDCl3 solution. The majority of the compounds are ionic,[R3PCl] Cl, in CDCl3 solution, in keeping with analogous species containing the heavier halogens [R3PX] X (X= Br or I), according to 31P-{1H} NMR studies ...
