Neighboring group participation in organometallic chemistry: Anchimeric assistance in catalyzed arene exchange reactions of (diarylalkane)tricarbonylchromium complexes

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.

The Friedel-Crafts acetylation of several (arene)tricarbonylchromium complexes have been investigated.From the results it is concluded that the tricarbonylchromium group deactivates to a small extent towards electrophilic substitution the ring to which it is attached.In the case of tricarbonyl(diphenylmethane)chromium (1; n=1), however, attack occurred on both rings to about an equal extent, possible explanations for this unexpected behaviour are advanced.
Neighboring Group Participation in Organometallic Chemistry: Internal Exchange in (Diarylalkane)tricarbonylchromium Complexes
Traylor, Teddy G.,Goldberg, Martin J.
, p. 3968 - 3973 (2007/10/02)
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
