Transition Metal Complexes of N-Heterocyclic and Mesoionic Carbenes: Structure, Materials and Catalytic Applications. (#195)

Since their discovery in the early 1990's, N-heterocyclic carbenes (NHCs) have become one of the most often employed ligands in transition metal catalysis, second only to the ubiquitous phosphine. The complementarity of these two ligand classes is a feature that has driven the synthesis of catalysts bearing both types of ligands, such as the Grubbs second generation metathesis catalyst. In addition to their use as ligands for polymerization catalysts, these ligands are also featured heavily in catalytic coupling and oxidative processes.

Recent advances in this area include the generation of novel types of carbene structures, including mesoionic carbenes and those incorporating atoms other than carbon and nitrogen into the backbone. In addition, applications in materials chemistry are beginning to appear, including in photoluminescent materials, functionalization of surfaces, liquid crystals, and redox-active main chain organometallic polymers.

This symposium will highlight three key areas of NHC/MIC chemistry: (1) the strong and continued development catalytic processes featuring NHCs and related ligands, (2) the synthesis of novel carbene structures, and (3) the use of NHC-type ligands in materials applications.
