Benzoylating methoxybenzene derivation by bismuth triflate under microwave irradiation
Main Article Content
Abstract
An efficient bismuth trifluoromethanesulfonate-catalyzed benzoylation of aromatic compounds and benzoic anhydride under microwave-irradiated solvent-free have been developed. Under solventless conditions, this process grants the preparation of aryl ketones in good yields and short reaction time. Especially, after reaction, Bi(OTf)3-catalyzed is easily recovered and reused five times without yield loss of the catalytic activity.
