Cyclic 1,2-diazylhydrazyls 3 have been detected by ESR spectroscopy during oxidation of the corresponding NH compounds 2.The N coupling constants are determined and confirmed by simulation and by (15)N labeling.The hydrazyls 3 react by dimerization to the corresponding tetrazenes of type 5 or by β scission to the diazyl azo compounds 4 and C radicals.The β scission of the radicals 3 is elucidated by UV/Vis detection of the azo compound 4b and reaction of 4b to Diels-Alder adducts.The alkyl radicals are trapped by nitrosobenzene (8) (ESR).
