Abstract An efficient synthesis of phthalocyanines prepared from ortho-substituted phthalonitriles is described. The precursor to these phthalocyanines, 3-nitrophthalonitrile, is a key reagent for syntheses of phthalonitriles substituted at the 3-position by means of nucleophilic aromatic substitutions. An example of this type of phthalocyanine, prepared from 3-(4-cumylphenoxy) phthalonitrile, is compared with the phthalocyanine derived from ...
