Nucleophilic catalysis of the migration of a tricarbonylchromium group from one ring to the other in diarylalkane tricarbonyl derivatives has been observed and compared with catalysis of external exchange. Internal catalysis by a neighboring tricarbonylchromium is also being reported. These results demonstrate the intermediacy of a chromium complex having three carbonyl groups, ketone, and two η2-bound arenes. The consequences of this result for metal exchange reactions are discussed.
Neighboring Group Participation in Organometallic Chemistry: Internal Exchange in (Diarylalkane)tricarbonylchromium Complexes

The rates of internal and external exchange of (diarylalkane)tricarbonylchromium complexes in benzene/cyclohexane mixtures have been determined.Neighbouring group participation is demonstrated in all complexes and follows an order with respect to ring siz
