The mechanism of the Friedel-Crafts acetylation of benzene was studied with in situ IR spectroscopy in ionic liquids at room temperature. The reaction of [bmim]+[Al2Cl7]- (1-butyl-3-methyl-imidazolium heptachloro dialuminate), acetylchloride and benzene leads to the formation of several key intermediates, including the AlCl3 adduct of acetylchloride, another species (A) with characteristic bands at 2200 and 1636/cm, and to the AlCl3 adduct of acetophenone. The possible structure of species A and the mechanism of the reaction were discussed. This is an abstract of a paper presented at the 221st ACS National Meeting (San Diego, CA 4/1-5/2001).
