The reaction of 10‐phenylphenolhiazine cation radical ( 1 ) with nitrite ion leads not only to 10‐phenylphenothiazine 5‐oxide ( 2 ) but also to 3‐nitro‐10‐phenylphenothiazinc 5,5‐dioxide ( 4 ), and two dinitro‐10‐phenylphenolhia/.ine 5‐oxidcs ( 5 and 6 ). The products ( 3‐6 ) appear to he formed from the nitration of 2 by nitrogen dioxide, the nitrogen dioxide arising from the reaction of nitric oxide (formed along with 2 when 1 reacts with nitrite anion) and oxygen.
