2,3-Bis(dibenzylamino)- and 2,3-bis[allyl(benzyl)amino]-2Z-butene-1,4-dinitriles are macrocyclised by reaction with magnesium propoxide in propanol to provide the corresponding (porphyrazinato)magnesium(II) derivatives, the structures of which are confirmed by X-ray crystallographic studies of the title magnesium and nickel(II) complexes; cyclisation of alternative diaminomaleonitrile derivatives gives the corresponding porphyrazinoctamines.

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

The synthesis and isolation of unsymmetrical porphyrazines bearing two, four, and six bis-(dimethylamino) functionalities has been achieved via the base-catalyzed cross-condensation of 1,2-dicyanobenzene 8 and bis(dimethylamino)maleonitrile 7. In addition, the benzo-fused hexaaminoporphyrazine dimer 10 was prepared from condensation of dinitrile 7 (in excess) with benzenebis(1,3-diiminopyrroline) 9
for the first time by treatment with metal salts, hexamethyldisilazane (HMDS) and p-toluene sulfonic acid (PTSA) in DMF at 120 °C. This reaction provides a new preparative method undermildconditions for direct synthesis of metalloporphyrazines having a variety of metals and substituted maleonitriles.
通过在 120 °C 的 DMF 中用金属盐、六甲基二硅氮烷 (HMDS) 和对甲苯磺酸 (PTSA) 处理,首次实现了从马来腈中制备游离碱和金属四氮杂卟啉的新型单步法。该反应为在温和条件下直接合成具有多种金属和取代马来腈的金属卟啉提供了一种新的制备方法。
