Authors review their works on elaboration of new synthetic approaches to heterocyclic analogues of phthalocyanine
– porphyrazines with fused fragments of pyridine, pyrazine, quinoline, quinoxaline, tetraazanaphthalene,
tetraazaantracene, thiophene and benzothiophene, and especially their lyophiliс tert-butyl substituted derivatives.
Special attention is given to preparation of tetracyanothiophene and tetracyanopyrazine, following condensation
of which leads to poly(heteroareno)porphyrazines having full conjugation over all macromolecular framework and
differing from polyphthalocyanines by the presence of rigid unsaturated аzаcrown-, thiacrown- or thiaazacrown
fragments. New high yield approach to the synthesis of tetraheteroarenoporphyrazine free bases from aromatic or
heteroaromatic o-dinitriles is also announced.
