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

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 HBF4 provided a straightforward access to 1,3-dicyclohexylimidazolium tetrafluoroborate (ICy·HBF4). 1,3-Dibenzylimidazolium tetrafluoroborate (IBn·HBF4) was obtained along the sam...
