New NHC ligand functionalised with indenyl and fluorenyl moieties have been synthesised. A number of metal complexes containing these ligands have also been synthesised and many characterised by X-ray crystallographic techniques.
A number of imidazolium salts functionalised with a cyclopentadienyl type moiety have been synthesised including: 1-[2-(9-9H-fluorenyl)ethyl]-3-(2,6-diisopropylphenyl)-2H-imidazol-1-ium bromide; 1-[2-(2,7-di-tert-butyl-9H-fluoren-9-yl)-ethyl]-3-(2,6-diisopropyl-phenyl)-3H-imidazol-1-ium bromide; 3-(2,6-diisopropylphenyl)-1-[2-(3H-inden-1-yl)-ethyl]-2H-imidazolium bromide; 3-(2,6-Diisopropyl-phenyl)-1-(3H-(4,7-dimethl)inden-1-yl)-ethyl}-3H-imidazolium bromide.

Abstract
New NHC ligand functionalised with indenyl and fluorenyl moieties have been synthesised. A number of metal complexes containing these ligands have also been synthesised and many characterised by X-ray crystallographic techniques.
A number of imidazolium salts functionalised with a cyclopentadienyl type moiety have been synthesised including: 1-[2-(9-9H-fluorenyl)ethyl]-3-(2,6-diisopropylphenyl)-2H-imidazol-1-ium bromide; 1-[2-(2,7-di-tert-butyl-9H-fluoren-9-yl)-ethyl]-3-(2,6-diisopropyl-phenyl)-3H-imidazol-1-ium bromide; 3-(2,6-diisopropylphenyl)-1-[2-(3H-inden-1-yl)-ethyl]-2H-imidazolium bromide; 3-(2,6-Diisopropyl-phenyl)-1-(3H-(4,7-dimethl)inden-1-yl)-ethyl}-3H-imidazolium bromide.
A number of main group metal complexes with ligands derived from the imidazolium salts have been synthesised including: 1-[2-(9-Fluorenyl)ethyl]-3-(2,6 di-iso-propylphenyl)-imidazol-2-ylidene potassium; 1-[2-(inden-1-yl)ethyl]-3-(2,6 diisopropylphenyl) – imidazol-1-ylidene potassium; 1-[2-((3,5-dimethyl)inden-1-yl)ethyl]-3-(2,6 diisopropyl-phenyl) –imidazol-l-ylidene potassium; 1-[2-(9-[2,7-Di-tert-butylfluorenyl)ethyl]-3-(2,6-di-iso-propylphenyl)-imidazol-2-ylidene potassium; 1-[2-(9H-fluoren-9-yl)ethyl]-3-(2,6 diisopropylphenyl)-3H-imidazol-1-yl silver bromide; 1-[2,5-dimethyl-2-(inden-1-yl)ethyl]-3-(2,6 diisopropylphenyl)-3H-imidazol-1-yl silver bromide; 1-[2-(9H-fluoren-9-yl)ethyl]-3-(2,6 di-iso-propylphenyl)-2H-imidazol-1-ylidene zinc HMDS bromide; 1-[2-(9H-fluoren-9-yl)ethyl]-3-(2,6 diisopropylphenyl)-2H-imidazol-1-ylidene zinc neopentyl bromide; 1-[2-(1-3H-indenyl)ethyl]-3-(2,6 di-iso-propylphenyl)-2H-imidazol-l-ylidene copper bromide.
