Iodine is shown to be an efficient catalyst for the Friedel-Crafts alkylation of arenes with a wide variety of aldehydes in toluene under 'open-flask' and mild conditions. In the presence of 10 mol % of iodine, the reaction of arenes with aromatic aldehydes gives the Corresponding triarylmethane derivatives (TRAMs), regioselectively, in good to excellent yields. On the other hand, a series of diarylalkane derivatives is synthesized smoothly by reaction with aliphatic alclehydes. (C) 2009 Elsevier Ltd. All rights reserved.
