Acid and complex-forming properties of tetrapyrazinoporphyrazines
摘要:
The reactions of octaethyl-and octaphenyltetrapyrazinoporphyrazines with dimethyl sulfoxide were studied. The compositions of the resulting complexes with proton-transfer were determined. The reaction of the formation of a magnesium(II) octaethyltetrapyrazinoporphyrazine complex in pyridine was studied. Kinetic parameters of the reaction were determined and assumptions on the reaction mechanism were made.

of a 20 π-electronsystem in the dianions. Contrarily, salt 3 was obtained at the monodeprotonation of H2T(PhnPyz)Pz macrocycle, and as a result, this macrocycle shows no alternation of bonds observed in 1 and 2. Salt 3 also preserves the position of the bands in the visible-NIR range in contrast to the reduced macrocycles. All these facts indicate the preservation of an 18 π-electronsystem characteristic
