Preparation of Substituted Tetrabenzotriazaporphyrins and a Tetranaphthotriazaporphyrin: A Route to Mono-meso-substituted Phthalocyanine Analogues

Article abstract of DOI:10.1021/jo00294a038

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 obtained.
