Abstract
1-Chloroalkyl isocyanates react with imidazole, 4(5)-phenylimidazole, and 4,5-dimethyl(phenyl)-imidazoles to give 5-aryl-5-trifluoromethyl-5,6-dihydro-7H-imidazo[1,5-a]imidazole-7-ones, and with benzimidazole affording 1-aryl-1-trifluoromethyl-1,2-dihydro-3H-imidazo-[1,5-a]benzimidazole-3-ones.
