Article abstract of DOI:10.1007/BF00528635

The syntheses of aryl-substituted octaaza analogs of phthalocyanine - tetra-2,3-(4,5-dipenylpyrazino)porphyrazin and its vanadyl complex - and also of the vanadyl complex of tetra-2,3-(4-phenylquinolino)porphyrazin - a tetraaza analog of naphthalocyanine - are described.A modified singlestage method for the synthesis of the previously reported tetra-2,3-(5-tert-butylpyrazino)porphyrazin is put forward.The electronic absorption spectra of the compounds synthesized have been studied in organic solvents and acid media - in sulfuric acid solution and in organic solvents with the addition of phenol or trichloroacetic acid.
