Abstract :
Naphthols were selectively coupled under sonication using Fe+3 impregnated pillared Montmorillonite K10 and TBHP as an oxidant. Considerable enhancement in the reaction rate was observed under sonication as compared to the reaction performed under silent condition. The activity of catalyst was compared with other Fe clay catalysts. Various parameters like solvent, catalyst and TBHP concentration has been studied. The heterogeneous active catalyst K10-FePLS120 was recycled without loss in activity and selectivity performance.
