In the last twenty years, N-heterocyclic carbenes (NHCs) have acquired considerable popularity as ligands for transition metals, organocatalysts and in metal-free polymer synthesis. NHCs are generally derived from azolium based salts NHCH+X− by dep

N-Heterocyclic olefin (NHO) can be generated by simple cathodic reduction of BDMImBF4-DMF solution or neat BDMImBF4 (BDMImBF4=1-butyl-2,3-dimethyl-1H-imidazolium tetrafluoroborate; DMF=dimethylformamide). In the latter case, the use of any organic so

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, wa

The electrochemical reduction of imidazolium-based ionic liquids (BMIm-X) leads to the formation of corresponding N-heterocyclic carbenes (NHCs). Owing to the peculiar reactivity of NHCs, solutions containing NHC in ionic liquid (IL) can be used in C

A simple electrolysis (under galvanostatic conditions) of the room temperature ionic liquid 1-butyl-3-methyl-1H-imidazolium tetrafluoroborate, BMIm-BF4, yields, after bubbling CO2 into the catholyte, the adduct NHC-CO2. The considerable stability of

N-Heterocyclic carbenes (NHCs), generated by electrochemical reduction under galvanostatic control of 1,3-dialkylimidazolium-based ionic liquids, were employed as catalysts in transesterification reactions in the parent, room temperature ionic liquid

In order to reveal the possible formation of free N-heterocyclic carbene (NHC) in DMF-azolium and acetate solutions, the proton exchange equilibrium between azolium cations and CH3COO− was investigated (by cyclic voltammetry) by adding CH3COOH or t

N-Heterocyclic carbenes (NHCs) are widely used as organocatalysts. Their reactivity (and instability) is related to their basicity and nucleophilicity, which, in turn, are linked to their scaffold. NHCs can be generated by chemical deprotonation or e

The activation of carbon dioxide has been obtained in O 2 /CO 2 saturated ionic liquids, via electrochemically generated O 2 − , at a less negative potential than the one of the direct cathodic reduction of CO 2 . This electrochemical activation ha
