Oxidative coupling of o-phenylenediamine has been previously reported via Lewis acids, TEMPO,1 or activity with horseradish peroxidase.2  Recently, the electronic properties of 2,3-diaminophenazine for use in conducting oligomers and polymers have gained interest.3  At the same time, interest in metal mediated synthetic methodologies are also gaining interest, and reports of uranium assisted reaction pathways are more prevalent.4 Here, we present the oxidative coupling of o-phenylenediamine forming 2,3-diaminophenazine in the presence of the synergists uranyl salts and tetracyanoplatinate.
