Abstract

Treatment of MgII complex of tert-butyl substituted 1,2,5-telluradiazolotribenzoporphyrazine with acetic or trifluoroacetic acid leads, along with the demetallation of the macrocycle, to the expulsion of the Te atom and formation of diimino- and dioxoporphyrazines. Detelluration upon treatment with CF3COOH in pyridine solution results in dimerization affording planar bisphthalocyanines with the bridge pyrazine moiety
