Anodic Cyanation of 1-Methylimidazoles
Yoshida, Kunihisa,Kitabayashi, Hirohito
, p. 3693 - 3696 (1987)
The electrooxidation of several 1-methylimidazoles was performed in MeOH that contains NaCN at a platinum anode in a divided cell.Replacement of an aromatic hydrogen by a cyano group occurred.With 1,2,4,5-tetramethylimidazole, the 2,5-addition of cyano groups to the imidazole ring was achieved, and besides side-chain substitution occurred concurrently.
