Investigation of nitrogen-containing heterocyclic free radicals
- 40 Downloads
Dimers of 4(5)-phenyl-5(4)-β-naphthyl-2-phenyl-substituted imidazolyl radicals were synthesized in order to study the effect of a β-naphthyl group on the stability of triaryl-imidazolyl radicals, and the rate constants and energies of activation for dissociation of the dimers were determined. The presence of a β-naphthyl group in the bistriarylimid-azolyl molecule facilitates its dissociation into radicals as compared with bistriphenyl-imidazolyl.
