General procedure: In a typical experiment, alcohol (10 mmol), aqueous NH3*H2O (30 mmol), FeCl4-IL-SiO2 (0.5 g), and CH3CN (10 mL) were added to a round-bottomed flask. Then, aqueous 30 % H2O2 (21 mmol) was gradually added into the reactor at room temperature. The obtained mixture was stirred at 30 C for appropriate time (Table 4). The reaction was monitored by TLC and GC. After completion of the reaction, the catalyst was recovered by filtration. Evaporation of the solvent under reduced pressure gave the crude product. Further purification was achieved by flash column chromatography on a silica gel (petroleum ether/ethyl acetate, 5:1) to give the desired product. Fresh substrates were then recharged to the recovered catalyst and then recycled under identical reaction conditions.
