First direct evidence of N-heterocyclic carbene in BMIm acetate ionic liquid. An electrochemical and chemical study on the role of temperature
Cyclic voltammetry provides the first direct evidence of N-heterocyclic carbene (NHC) presence in neat 1-?butyl-3-methylimidazolium acetate ionic liquid
(BMImAcO) at 120°C. The NHC existence, proved by its oxidation current in cyclic voltammetry, was confirmed by the formation of a PhCHO-NHC adduct in pure ionic liquid. The role of the temperature was considered.
