Inside changes! In striking contrast to the trans-bromination of the free acid, bromination of the bridging cinnamato ligand in 1 proceeds highly diastereoselectively to give the syn-brominated complex 2. A possible explanation for this is that the bromination of 1 proceeds within a confined environment. Since the brominated products can be liberated from the binding pocket of the dinuclear complexes, the metal complexes can be used as reagents for the cis-bromination of olefins with anchoring RCO2− functions.
