Chemoselective C-benzoylation of phenols by using AlCl3 under solvent-free conditions

S. V. Gaikwad, B. R. Nawghare, P. D. Lokhande

Abstract


Substituted phenols were chemo-selectively reacted with benzoylchloride in presence of aluminum chloride under solvent-free condition to afford the corresponding 2'-hydroxy aryl benzophenones in excellent yields (72-96%). Naphthol benzoylation resulted in lower yields as compared to phenols. Both reactions completed in 5-10 min with quantitative yields providing excellent control over regioselectivity of products.
