Abstract
The reaction of 1-hydroxy-1-methyl-1H-3-(1-oxo-6-tert-butylisoindolin-3-ylidenemethyl)-5-tert-butylisoindole, which is the product from the condensation of potassium 4-tert-butylphthalimide and malonic acid, with phthalonitrile or 3-iminophthalimide leads to the formation of a mixture of the tert-butyl-substituted mono-, di-, and triaza analogs of zinc tetrabenzoporphin. The mixture was separated by chromatography on aluminum oxide. The zinc complex of di(4-tert-butylbenzo)di-benzodiazaporphin is demetallated by the action of HCl in acetic acid. The characteristics of the synthesized compounds are given.
