Free Radical Reactions of N-Heterocyclic Compounds. VIII. ESR-Investigations on the N,N-Bond Cleavage Reaction of Cylic 2,2-Diacyclhydrazinoxyls2,2-Diacylhydrazinoxyls (2) undergo decomposisition to new nitroxides 3 in the presence of bis (acetylacetonato) cobalt (II), tert.-butyl hydroperoxide and an alcohol (i.e. methanol, ethanol, i.-propanol). These new radials 3 are spin trap products of nitrosoarenes, formed by a fragmentation process of 2 and of ligand radicals, generated from bis (acetylacetonato) cobalt (II) by oxidation with tert.-butyl hydroperoxide. The e. s. r. data of the radicals 2, 3 and of the 3-isomeric radicals 5 and 6 are compared.
