This communication presents a new preparation for complexes of the general structure [CpRRhCl2]2 (CpR = a substituted cyclopentadienyl ligand). Using isopropyl alcohol as the solvent in place of ethanol prevents the formation of Rh-carbonyl side products during synthesis. This procedure also affords higher yields of many [CpRRhCl2]2 derivatives with significantly shorter reaction times in comparison to previous methods. This procedure is applied to a variety of complexes bearing sterically diverse cyclopentadienyl ligands.
