Spectroscopic And Electrochemical Observation Of Hydrogen-Bonded Imidazole And 2-Aminoimidazole Clusters

Abstract

The electroreductions of imidazole and 2-aminoimidazole were investigated on a Pt electrode in acetonitrile containing tetrabutylammonium tetrafluoroborate with and without the presence of HBF4. The effects of lithium and tetrabutylammonium ions on the electroreduction and FTIR and H-1 NMR results were also compared. The feasibility of the formation of intermolecular hydrogen bonds was elucidated by the use of the theoretical calculations. Electroreduction waves were interpreted by the existence of the hydrogen-bonded clusters in acetonitrile containing tetrabutylammonium tetrafluoroborate.
