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.
