| Abstract | 1 The present study involves a simple one step green route to synthesis of anthraquinone derivatives via Friedel-Crafts reaction under solvent free conditions using solid acid catalysts. Two types of solid acid catalysts have been synthesized, characterized and their potential utility towards synthesis of anthraquinone derivatives has been explored and compared. M(IV)PWs (M(IV) = Zr, Ti and Sn, and PW = Phosphotungstate) mixed materials of the class of tetravalent metal bianionic acid (TMBA) salts have been synthesized by sol-gel route while 12-Tungstophosphoric acid (12-TPA) has been supported onto ZrO 2 , TiO 2 and SnO 2 by process of anchoring and calcination to result in materials with similar elemental composition. The highlighting features are that the anthraquinone derivatives are obtained in a single step under solvent free conditions with good % yields with added advantages of regeneration and reuse of M(IV)PWs upto three catalytic runs without significant loss in % yields of the products formed. |
