    摘要: Pyrolysis of 2-diazo-4,5-dicyano-2H-imidazole in the presence of certain halohydrocarbons yields 1-hydrocarbon substituted-2-halo4,5-dicyanoimidazoles. Pyrolysis of the same starting material in the presence of hydrocarbons, certain other halohydrocarbons, or certain Group I metal salts, yields 2-substituted-4,5-dicyanoimidazoles.
