SYNTHESIS OF SOME HEPTAZINE DERIVATIVES

Abstract
New derivatives of heptazine were prepared from 2,5,8-trichloroheptazine by a Friedel–Crafts reaction and Pd-catalyzed amination. New triamino-substituted heptazine derivative represents a soluble carbon nitride monomeric unit suitable for the assembly of metal–organic and covalent–organic frameworks. Aromatic substituents in heptazine ring can be displaced by an alkylamine in a pseudo-nucleophilic substitution reaction.
