BIAN-NHC Ligands in Transition-Metal-Catalysis: A Perfect Union of Sterically Encumbered, Electronically Tunable N-Heterocyclic Carbenes?
TL;DR: BIAN-NHC ligands take advantage of the stronger σσ-donation, lower lying LUMO orbitals, the presence of an extended ππ-system, and the rigid backbone that pushes the N-wingtip substituents closer to the metal center by buttressing effect, resulting in a significantly improved control of the catalytic center and enhanced air-stability of BIAN- NHC-metal complexes at low oxidation state.
