Phthalocyanines and related compounds: XLV. Nucleophilic substitution of chlorine in tetrachlorophthalonitrile: Synthesis of aryloxy-aubstituted phthalonitriles and phthalocyanines derived from them
摘要:
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 gives aryloxychloro-substituted phthalocyanines having the absorption band in the near-IR range.
