Difunctional and symmetric phthalonitriles were synthesized by nucleophilic substitution of brome and nitro-group in 4-bromo-5-nitro-phthalonitrile for residues 4-amino-, 4-hydroxyl- and 4-sulfanyl benzoic acid. Symmetrical and difunctional substituted cobalt phthalocyanines were obtained by template synthesis based on mentioned phthalonitriles. Their spectral properties and catalytic activity in aerobic oxidation of sodium N,N-carbomoditiolate were investigated.

Phthalonitriles with fragments of 4-hydroxy, 4-mercapto and 4-aminobenzoic acids were synthesized by nucleophilic substitution in 4-bromo-5-nitrophthalonitrile. The synthesized phthalonitriles were used to prepare octasubstituted cobalt phthalocyanines by

4,5-Dichloro-1,2-dicyanobenzene (5) was prepared in an overall yield of 49% from 4,5-dichloro-1,2-benzenedicarboxylic acid (1). The reactions of 5 with phenols, thiophenol and 1-propanethiol led in a nucleophilic displacement reaction to the 4,5-bis(aryloxy)-, 4,5-bis(phenylthio)- and 4,5-bis(propylthio)-1,2-dicyanobenzenes 6 which were converted in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene in high yields to octasubstituted phthalocyanines (tetrabenzoporphyrazines) 7. Some compounds 7 contain eight free phenolic, carboxylic acid or pyridyl groups.
