Reaction Conditions:
with hydrogen in ethanol at 20; under 760.051 Torr; for 3 h;
Steps:
3. Applications of treated catalysts in hydrogenation reactions. General procedure.
General procedure: A mixture of substrate (0.2 mmol) and Pd/Al2O3Si (6.4 mg, 1 mol%) in ethanol (2 mL) was stirred under hydrogen atmosphere (H2 balloon pressure) at room temperature. The progress of reaction was monitored by TLC analysis or GC-MS. After the reaction was completed, the reaction mixture was filtered, and the catalyst was washed with ethanol. The solvent in filtrate was removed by vacuum to give the crude product. The purified product was obtained by column chromatography or recrystallization. After each cycle, the palladium residue in the reaction mixture solvent was determined by ICP-OES.
