Synthesis and Characterization of Triazole and Imidazole Based Carbene Iridium (I) Complexes

N-heterocyclic carbenes hav sometimes been considered alternatives to phosphines as spectator ligands in homogeneous catalysis, and share with them the possibility of tuning catalyst activity by varying the substitution scheme of the ligand. The triazole and imidizole carbenes have been relativelty little studied thus far, but are very promising ligands for catalytic applications. A series of new triazole and imidazole based carbene iridium (I) complexes will be synthesized and characterized using multinuclear NMR, IR, and elemental analysis. Their catalytic activity will be studied in organic sythnesis.
