Electrogenerated N-Heterocyclic Olefins: Stability and Catalytic Ability
N-Heterocyclic olefin (NHO) can be generated by simple

the use of any organic solvent and chemical base is avoided. To
prove the presence of NHO, its adduct with benzaldehyde was
isolated. The electrochemical behavior of NHO is very similar to
