Bismuth (III) triflate-catalyzed Friedel-Crafts reactions between benzofuran and aldehydes in different solvents were investigated. Bis(benzofuranyl)methanes were obtained with good yields when acetonitrile was used as solvent vent, while in the case of nitromethane the multi-component reaction products, 2-benzofuran-1-nitroalkanes, were formed under similar conditions. A plausible mechanism is given.
