Nitro-substituted porphyrazines

This nitration of tetra (tert-butyl)porphyrazine and its metal complexes with different nitrating agents has given their mono-, di-, tri-, and tetra-nistro-derivatives; the metal complexes have also been obtained by the metallation of the corresponding metal—free nitroporphyrazines. The structure of the synthesized compounds has been confirmed by electron and mass spectra, and by PMR spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 30–35, January, 1994.
