Abstract (300 words maximum)
Catalysts lower the energy barrier of different reactions and can provide greater selectivity with higher yields and therefore are of particular interest to material production. Improvement in catalysts can lead to greener production and a decrease in cost. N-heterocyclic carbenes (NHCs) have been recognized as a powerful class of ligands to metals, perhaps most notably in catalysis. This presentation reports a novel family of bis-NHC ligands. This family links the N-alkylated benzimidazolium moieties by a bridge providing a rigid structure for the generation of novel bis-NHCs and their corresponding metallic complexes. The unique structure of this family allows for the formation of bimetallic complexes, MCOPs, and supramolecular structures. These complexes allow for great versatility in catalytic properties, solubility, and selectivity. The synthesis and characterization of iridium complexes with these bis-NHC ligands will be presented.
