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 vitamin 606 $aLigands 606 $aHeterocyclic compounds 606 $aTransition metal complexes 615 0$aLigands. 615 0$aHeterocyclic compounds. 615 0$aTransition metal complexes. 676 $a541.2242 676 $a547.05 686 $aCHE 330f$2stub 686 $aCHE 612f$2stub 686 $aCHE 670f$2stub 700 $aKu?hl$b Olaf$01700487 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830352403321 996 $aFunctionalised N-heterocyclic carbene complexes$94083517 997 $aUNINA
