Highly Efficient Synthesis of Chloro‐ and Phenoxy‐Substituted Subphthalocyanines

Abstract

Abstract A highly efficient method for the synthesis of chloro‐substituted subphthalocyanines employing a 1 M boron trichloride solution in p ‐xylene is described and compared to other previously described results. The substitution reaction of the axial chlorine atom by a phenoxy group has been optimized. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
