• Efficient dinuclear catalysts: A complex of {Rh2(OAc)4} with two N‐heterocyclic carbenes (NHCs) at the axial positions catalyzes the arylation of aldehydes (see picture; R=alkyl, aryl). DFT calculations reveal subtle stereoelectronic effects resulting from the NHC coordination to the dirhodium(II) complex and suggest that complexes with one axial NHC ligand are the catalytically active species.
