Abstract

The oxidative polymerization of o‐phenylenediamine was studied under a variety of conditions. At room temperature the reaction of o‐phenylenediamine with ammonium persulfate in HCl acid medium gives a dimer, 2,3‐diaminophenazine. The same reaction at 70°C results in a trimer with an open structure, [3‐amino‐2(3,4‐diaminophenylamino)]‐phenazine hydrochloride. At 118°C, the oxidative polymerization in glacial acetic acid medium gives poly(aminophenazine) acetate, analogous to polyaniline. However, either because of the atactic nature of the polymer and the consequences of this on the stability of charge carriers or because protonation occurs at localized amines, no electrical conductivity was found.

## Abstract Practicable syntheses of 1‐amino‐ and 1:3‐diamino‐phenazines are described for the first time. These substances (and a byproduct, 1‐hydroxyphenazine) thus become relatively accessible and may prove of interest as redox indicators or as material for further syntheses.
