Cyanation of the imidazole ring was explored by the addition of cyanogen chloride to imidazol-2-ylidenes. Backbone cyanation often occurs when hydrogen atoms are in the C-4/5 positions. When tetrasubstituted imidazol-2-ylidenes are employed, 2-cyanoimidazolium halide salts can be isolated. These...
