The state and stability of magnesium(II) complexes with azaporphyrins in the proton-donor medium

The state and stability of magnesium complexes with various azaporphyrins in the proton-donor media containing acetic acid have been studied. Kinetic parameters of the complexes dissociation have been determined, possible reactions mechanisms have been pr

Phthalocyanines and related compounds: XXXVI. Synthesis of tetraazachlorin and tetraazaporphine from succinonitrile

A new method of synthesis of tetraazaporphine and a previously unknown tetraazachlorin via reaction of succinonitrile with lithium dimethylaminoethoxide in dimethylaminoethanol or with lithium pentoxide in pentyl alcohol, with simultaneous oxidation of intermediate hydrogenated forms with air oxygen is proposed. A possible scheme of the reaction is discussed, and optimal conditions for selective synthesis of both compouds in yields of up to 18% are found. The product obtained with lithium pentoxide contains an admixture of pentyloxytetraazaporphine. Tetraazachlorin is quantitatively oxidized to tetraazaporphine by short heating in acetic acid. The structure of tetraazachlorin is confirmed, and its electronic absorption spectra are discussed.
