Aromatic primary amines substituted with electron donating groups such as methoxy and methyl at the para position undergo nucleophilic aromatic substitution (SNAr) reactions on 4,5-dicyano-2-fluoro-1-methylimidazole(2) in dimethyl sulfoxide at room temperature to give secondary amines substituted with dicyanoimidazolyl groups. Aromatic primary diamines and hydrazine similarly react with 2 to give new
