Kinetics of internal and external arene exchanges in benzene as solvent have been studied with tricarbonylchromium complexes of ditolylmethane, ditolylcyclopropane, dimesitylmethane, and dibenzobicyclo[2.2.2]octadienes. These studies define the stereoelectronic requirements for arene exchange and document the stepwise process in which the bonding in the displaced arene proceeds from η6 to η4 to η2. A new intermediate, (arene)3Cr(CO)3, is indicated by the catalyzed exchange reactions of some of these compounds.
