A new method was developed for the synthesis of novel Schiff bases containing the anthraquinone moiety using dodecatungstosilicic acid/P 2 O 5 under solvent-free conditions at room temperature. The reaction was completed in 1-3 minutes with excellent yields. This method was found to be very efficient, easy and hazardous-free for the synthesis of azomethines. The development of these types of methodologies in synthetic chemistry may contribute to green chemistry. The structures of synthesized
