Abstract Electron-rich N-heterocyclic carbene (NHC) ligands have many advantages in synthesizing stable transition metal catalyst complexes. Because of the strong sigma donation ability of NHC ligands, metal ions strongly coordinate to NHC ligands, leading the formation of metal, which are oxygen and moisture stable. Bidentate NHCs behave like hemilabile ligands and can easily generate vacant sites in the metal complex. In addition, NHC is easy to introduce additional functional groups. NHC complexes with alcohol, alkoxide, phenoxide, ether, N-heteroaryl, oxazoline, amino and amido have been reported. These additional groups mediate interactions between the ligand and the reactants or between the ligand and the catalyst, which increases the reaction rate and selectivity. In this study, we have made various structurally modified Iridium (III) bis-NHC complexes, which are employed in the conversion of amines to alcohols.
