Treatment of MgII complex of tert-butyl substituted 1,2,5-telluradiazolo[3,4-b]tribenzo[g,l,q]porphyrazine with SeO2 in dichloromethane leads to direct substitution of Te by Se, while the reaction with diaminomaleonitrile in ethanol affords (5,6-dicyanopyrazino)[2,3-b]tribenzo[g,l,q]porphyrazines. The obtained results demonstrate that 1,2,5-telluradiazoloporphyrazines can be used as synthetic analogues of vicinal diamino-, diimino- and dioxoporphyrazines..
