The synthesis, by treatment of phthalonitriles or 6-tert-butyl-2, 3-dicyanonaphthalene with Grignard reagents, of novel substituted derivatives of tetrabenzotriazaporphyrins and a substituted tetranaphthotriazaporphyrin are described. Mono-meso-substituted tetrabenzotriazaporphyrins, soluble in organic compounds, were the major products, but byproducts of phthalocyanines and, in one case, tetrabenzodiazaporphyrins were ...
