Yield:-

Reaction Conditions:

at 210; for 0.25 h;Microwave irradiation;

Steps:

4 Example 4: Synthesis of Phenazine and 2,3-Dihvdroxyphenazine
1.2-Dihydoxybenzene (0.3 g, 2.8 mmol) and 1,2-phenylenediamine (0.3 g, 2.8 mmol) were heated in a microwave vial to 210 °C for 15 minutes. The melt solidified, was cooled to room temperature and washed several times with water. The insoluble product (0.2 g) contained phenazine and 2,3-dihydroxyphenazine according to HPLC and absorption spectroscopy. Washing the product mixture with 2 M aqueous sodium hydroxide yielded the desired phenazine.
