A novel and efficient synthesis of bis(benzofuranyl)methanes and 2-benzofuran-1-nitroalkanes catalyzed by Bi(OTf)3

10.1139/V08-091

The study investigates the synthesis of bis(benzofuranyl)methanes and 2-benzofuran-1-nitroalkanes catalyzed by Bi(OTf)3. Benzofuran and various aldehydes are the main reactants. In acetonitrile solvent, Bi(OTf)3 catalyzes the Friedel–Crafts alkylation reaction between benzofuran and aldehydes to produce bis(benzofuranyl)methanes with good yields. When nitromethane is used as the solvent, the reaction forms 2-benzofuran-1-nitroalkanes as the major products. The study explores different metal triflates as catalysts and finds Bi(OTf)3 to be particularly effective and environmentally benign. The influence of various factors such as solvent, reaction temperature, and the type of aldehyde on the reaction outcomes is examined. The proposed mechanisms for the formation of the products involve the attack of benzofuran on intermediates formed in the presence of Bi(OTf)3.
