The X-ray structure of the complex surprisingly revealed that the substrate is not coordinated via the C-C double bond and one carboxylate oxygen, but instead via the two carboxylate oxygens and the quaternary carbon [C(2)] atom. Formally the acidic functions of the substrate had been completely deprotonated and the methylene group had been already converted into a methyl group via H-transfer. The tetrafluoroborate anion was no longer present in the crystal as the counterion. Thus, the complex represents a neutral Rh(III) alkyl complex, compare Reference [3]

Due to the limited solubility of the substrate in methanol higher substrate-to-catalyst ratios could not be investigated. In an experiment were a 100-fold substrate excess was used, about half of the substrate, which was dissolved by heating, recrystallized immediately with cooling of the sample

This effect may be caused by an increasing stability of the aryl-bridged dimers with decreasing temperature. A further possible explanation is the disturbance of the thermodynamic equilibrium between the solvent complex and the above mentioned dimers due to the fact that the observed catalyst-substrate complex is mainly formed from the solvent complex
