Synthesis and characterization of new metal-free and metallophthalocyanines containing macrocyclic moieties

The synthesis and characterization of new metal-free 7 and metallophthalocyanines 8, 9 carrying macrocyclic N2S2O4 donor groups on peripheral positions have been investigated. Phthalonitrile derivative 6 was synthesized according to Rosenmund von Braun procedure from compound 5. The novel compounds were characterized by elemental analysis, IR, 1H and 13C NMR, UV–Vis and MS spectra data.
