The synthesis and characterization of the chiral bifunctional NHC ligands based on the imidazo­[1,5-a]­pyridine (ImPy) scaffold are described. These ligands possess a fluxional biaryl axis and a chiral center. The configurational stability of the biaryl axis in their gold­(I) complexes is investigat...
