Acetate ion can deprotonate thiazolium cations to give the free NHC in DMF.
- •
Acetate ion cannot deprotonate imidazolium cations to give the free NHC in DMF.
- •
Cyclic voltammetric analysis can evidence NHC in azolium and acetate solutions.
- •
The thiazolium and acetate couple in DMF can catalyze the benzoin condensation.
- •
The imidazolium and acetate couple in DMF cannot catalyze the benzoin condensation.
