Abstract
A number of imidazoles were obtained by the reaction of substituted benzils with aldehydes of the carbazole series. Chlorobenzene solutions of the imidazoles take on a green coloration on oxidation with lead dioxide. The presence of free radicals in these solutions is confirmed by the ESR spectra and by the reaction with hydroquinone, diphenylamine, carbazole, and α,α-diphenyl-β-picrylhydrazine.
