Reactions of 2-chloroformylhydrazones of aromatic aldehydes or ketones 2 with various hydrazines were converted to monocarbonohydrazone derivatives 3 or 5 and/or tetrahydro-1,2,4,5-tetrazin-3(2H)-one derivatives 6,7.By oxidation with lead dioxide, compounds 6 were transformed into stable 3,4-dihydro-3-oxo-1,2,4,5-tetrazin-1(2H)-yl radical derivatives 8.
