Electrophilic Substitution in (Arene)tricarbonylchromium Complexes. Part 1.

von Rosenberg, Joseph L.,Pinder, A. Reginald

, p. 747 - 752 (2007/10/02)

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.
