The oxidation of beta-oxonitrones, derivatives of pyrroline and imidazoline, afforded symmetric dimers with a C-C bond and dehydrodimers with a C = C bond. Oxidation of the trifluoroacetyl imidazoline derivative afforded an asymmetric dimer. The oxidative dimerization of endocyclic beta-oxonitrones, derivatives of pyrroline, proceeded much faster than that of exocyclic beta-oxonitrones, derivatives of imidazoline. Imidazoline derivatives containing a perfluorophenyl or cyano group at the alpha-carbon atom on the nitrone group also underwent oxidative dimerization.
