Direct nucleophilic substitution of primary and secondary amines for hydrogen in quaternary phenazinium salts containing an additional positive charge in the aliphatic part of the molecule was carried out. The substitution proceeds successively in positions 2 and 7, which allows selective introduction of different substituents into the heterocycle.

Two different approaches are offered for the synthesis under mild conditions of disubstituted phenazinium and benzo[a]phenazinium salts. Direct nucleophilic substitutions by primary and secondary amines in quaternary phenazinium salts containing an additional positive charge in the aliphatic part of the molecule were carried out. The substitution proceeds successively in positions 2 and 7, which allows
