Abstract

Para-toluene sulfonic acid embedded on nano silica (ρ-TSA@nano SiO2) has beensynthesized via a simple procedure and characterized by fourier transform infrared spectroscopy(FT-IR), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM)techniques. The synthesized NANOCATALYST has been utilized to accelerate the one-pot multicomponentcondensation reaction of isatins, anilines, and acetone to obtain the corresponding 1'-aryl-2'-(2-oxoindolin-3-yl)spiro[indoline-3, 5'-pyrroline]-2, 3'-diones at water media under reflux conditions. Utilization of H2O as available and green solvent, excellent yields of products, short reactiontimes, avoidance of by-products which could be obtained via Aldol condensation of acetone, easily-handle, inexpensive, non-toxic, and heterogeneous nano acid catalyst are some advantageousof the reported method. The recovery and reusability of the nano catalyst has been examined forfour runs without activity loss.
