Insertion of chloral into P-Br bond of phosphoranes

Abstract

Chloral inserts into the P-Br bond of pyrocatechintribromophosphorane with the formation of stable mono-, di- and tri(1-bromo-2,2,2-trichloroethoxy) phosphoranes and, also, into the P-Br bond of bis (pyrocatechin) bromophosphorane with the formation of 1-bromo-2,2,2-trichloroethoxybis (pyrocatechin) phosphorane. © 1990 Plenum Publishing Corporation.
