| Abstract: | By alkylation of 3,6-dihydroxyphthalonitrile with 1-bromo-2-phenoxyethane 3,6-bis(2-phenoxyethoxy) phthalonitrile was obtained. A random condensation of the nitrile with 2,3-dicyano-5,6-diphenylpyrazine in 1-butanol in the presence of lithium 1-butanolate porphyrazines were synthesized of symmetric and unsymmetrical structure, and their spectral characteristics were investigated. |
