高效的双核催化剂：{Rh 2（OAc）4}与两个位于轴向位置的N-杂环卡宾（NHC）的配合物催化醛的芳基化反应（见图; R=烷基，芳基）。DFT计算揭示了微妙的立体电子效应导致的NHC协调的dirhodium（II）配合物，并建议与一个轴向NHC配体的配合物的催化活性物种。
(Chemical Equation Presented) Efficient dinuclear catalysts: A complex of {Rh 2 (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.
