与有机盐共价结合的过渡金属络合物为探索离子液体介质中的催化问题提供了独特的机会。乙酸盐与连接至羧酸的咪唑鎓官能团进行配体交换，得到所需的金属缀合物。研究发现，改性二铑(II)二聚体是使用重氮乙酸乙酯进行苯乙烯分子间环丙烷化反应的有效催化剂。
A transition metal complex covalently bound to an organic salt offers a unique opportunity to explore issues of catalysis in an ionic liquid medium. Ligand exchange of acetate with an imidazolium functionality tethered to a carboxylic acid afforded the desired metal-conjugate. The modified dirhodium(II) dimer was found to be an effective catalyst in the intermolecular cyclopropanation reaction of styrene using ethyl diazoacetate.
