Abstract
The rate constants and activation energies for homolytic dissociation of 2,2′-di[α (β)-naphthyl]-, 2,2′-diquinolinyl-, and 2,2′-di(9-acridinyl)-4,4′,5,5′-tetraphenyldiimidazolyls in toluene in the presence ofα,α-diphenyl-β-picrylhydrazine were determined. The degrees of dissociation of the diimidazolyls were found. The effect of substituents on the stability of imidazolyl radicals is discussed.
