Abstract

 A green, efficient, chemoselective, facile and clean procedure is described and discussed for the synthesis of α , α '-bis (substitutedbenzylidene) Cycloalkanones in solvent-free conditions. The condensation reaction was carried out through the reaction of aromatic Aldehydes with Cycloalkanones in the presence of Fe3O4@WO3 (Fe3O4@WO3-EAE-SO3H (III)) nanoparticles as the catalyst. The nanostructured catalyst with the spherical shape, particle size in the range of 7-23 nm and superparamagnetic behavior may be referred as an excellent replacement for Brø nsted acids. The reaction proceeds rapidly at room temperature, giving high yields of products. No self-condensation product was produced. Easy separation of the catalyst from the reaction mixture by means of an external magnetic field and re-using up to seven times without loss of activity are the salient features of the present method.
