Ni(OAc)(2) in chlorobenzene and dimethylformamide. Both free-base and nickel porphyrazines (6 and 7) were readily nitrated by nitrogen dioxide in CH(2)Cl(2), yielding dinitroporphyrazines 18 and 19, respectively. Electrochemical studies have shown that porphyrazinehexamine 2 is easy to oxidize, having the first oxidation at E(1/2) = - 0.18 V, which is 0.91 and 1.04 V lower than that of 4 and 6, respectively
