N-Heterocyclic Carbenes (NHC) on Surfaces

N-Heterocyclic Carbenes (NHCs) are powerful ligands in catalysis due to their strong electron-donating properties and their ability to form very stable bonds to transition metals.[1] Thus, they are used as ligands to stabilize and modify nanoparticles or flat metals surfaces, since they outperform well established phosphine or thiol ligands regarding structural flexibility, electron-donating properties and stability. As an example, our group discovered the ballbot-type motion of NHCs on metal surfaces[2] or the catalyst activation for a heterogeneous Buchwald-Hartwig reaction.[3] Future work in this area will include studies about the fundamental behavior of NHCs on surfaces (rotation, electronic activation, 2D networks) and fine tuning of heterogeneous catalysts towards higher activity, selectivity and stability.
