Studies on Cinnolines. V. Cinnoline Dioxide

Cinnoline dioxide (IV) and indazole (V) were obtained in addition to the monoxides on oxidation of cinnoline (I) with hydrogen peroxide in acetic acid. The structure of IV was confirmed by chemical and physico-chemical methods of UV, IR and NMR spectrometry and by polarographic reduction.
