The use of N-heterocyclic carbenes to modify homogeneous metal catalysts is widespread, however despite the versatility of these complexes, the high metal–NHC bond strength and oxidative stability of NHC–ligated metals, and the ease of synthesis of NHCs, there have been only a handful of reports of mostly ill-defined surfaces funtionalized by NHCs.
We will describe the modification of Au(111) surfaces by common N-heterocyclic carbenes. Depending on the deposition method, molecular ordering on the surface is observed along with
remarkable stability.
The use of NHCs as ligands for transition metal complexes rather than surfaces, specifically complexes of Rh and the use of these complexes in catalysis including C–H activation will be described.
Finally, we will show the versatility of these ligands by their important contributions to the new
area of borenium-based catalysis where transition-metal free catalysts are used to affect hydrogenation of C–N double bonds with hydrogen gas.
