Abstract

original image

Triple play: A novel triphenylene-based tris(N-heterocyclic carbene) ligand with D3h symmetry and a highly π-delocalized system has been prepared and coordinated to palladium and gold (see figure). The catalytic activities of the new complexes have been compared with those of related benzimidazolylidene and a triptycene-based tris(N-heterocyclic carbene) complexes in three reactions.
