Abstract
trobenzylidene)-3,5-di-tert-butyl-4-hydroxyaniline (3a) and N-(2-azido -5-nitrobenzilidene)aniline (3b), when heated in dimethylformamide yie lded 3,5-di-tert-butyl-4-hydroxyphenyl)-5-nitroindazole (4a) and 2-phe nyl-5-nitroindazole (4b), respectively. The structure of 4b was confir med by X-ray analysis. A stable phenoxyl radical was shown to originat e from the oxidation of 4a with lead (Iv) dioxide.
