Efficient synthetic protocols for the preparation of common N-heterocyclic carbene precursors

The one-pot condensation of glyoxal, two equivalents of cyclohexylamine, and paraformaldehyde in the presence of aqueous HBF(4) provided a straightforward access to 1,3-dicyclohexylimidazolium tetrafluoroborate (ICy·HBF(4)). 1,3-Dibenzylimidazolium tetrafluoroborate (IBn·HBF(4)) was obtained along t...
