The performance of these molecules can be improved and tuned by functionalisation. Functionalised carbenes can anchor free carbenes to the metal site, introduce hemilability, provide a means to immobilise transition metal carbene catalysts, introduce chirality, provide a chelate ligand or bridge two metal centres. NHC can be attached to carbohydrates and campher, derived from amino acids and purines, they can be used as organocatalysts mimicking vitaminLigandsHeterocyclic compoundsTransition metal complexesLigands.Heterocyclic compounds.Transition metal complexes.541.2242547.05CHE 330fstubCHE 612fstubCHE 670fstubKühl Olaf1700487MiAaPQMiAaPQMiAaPQBOOK9910830352403321Functionalised N-heterocyclic carbene complexes4083517UNINA
