Electrochemical Formation of Indazoles from Tropone Tosylhydrazones: Electrochemical Oxidations of Sodium Salts of Tosylhydrazones of Tropone and 2-Phenyltropone
Electrochemical oxidations of the sodium salts of tropone and 2-phenyltropone tosylhydrazones afforded 2-tosyl-2H-indazole and 1-tosyl-7-phenyl-1H-indazole, respectively. The reactions proceeded through the cyclizations of the corresponding hydrazyl radicals generated by electrochemical one electron oxidations of the hydrazone anions.
