Free Radical Reactions of N-Heterocyclic Compounds, X[1]. - Radical Reactions of Cyclic 1,2-DiacylhydrazinesCyclic 1,2-diacylhydrazyls 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 15N labeling. The hydrazyls 3 react by dimerization to the corresponding tetrazanes of type 5 or by β scission to the diacyl 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).
