- Free Radical Reactions of N-Heterocyclic Compounds. VIII. ESR-Investigations on the N,N-Bond Cleavage Reaction of Cyclic 2,2-Diacylhydrazinoxyls
-
2,2-Diacylhydrazinoxyls (2) undergo decomposition 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.
