Phthalocyanines and related compounds: XLV. Nucleophilic substitution of chlorine in tetrachlorophthalonitrile: Synthesis of aryloxy-aubstituted phthalonitriles and phthalocyanines derived from them
Nucleophilic substitution of chlorine in tetrachlorophthalonitrile by the reaction with aryloxy anions is studied. Depending on the reactant ratio, the products of substitution of one, two, and/or three chlorine atoms are formed. Their tetramerization giv
