在乙腈的酸性水溶液中 ,考察了 Pd Ac2 (醋酸钯 ) /Fe Pc(酞菁铁 )催化氧化环戊烯合成环戊酮的催化活性 ,讨论了影响该反应活性的因素及其反应机理。实验结果表明 ,该催化体系对环戊烯的羰基化显示出较高的催化活性 ,反应 1 0 min,反应的平均吸氧速率为 4.2 5× 1 0 -2 mmol/min,环戊酮的收率可达 83%。在乙醇的酸性水溶液中 ,Pd Ac2 /BQ(苯醌 ) /Fe Pc催化环戊烯氧化合成环戊酮的活性高于 Pd Ac2 /Fe Pc的活性 ,反应的平均吸氧速率分别为 1 .45× 1 0 -2 mmol/min,9.0×1 0 -3 mmol/mi
The catalytic activity of Pd Ac2 (palladium acetate) / Fe Pc (iron phthalocyanine) for the cyclopentanone synthesis of cyclopentene was investigated in acidic aqueous solution of acetonitrile. The factors affecting the reaction and the reaction mechanism were discussed. The experimental results showed that the catalytic system showed high catalytic activity for cyclopentene carbonylation. The average oxygen uptake rate was 4.2 5 × 10-2 mmol / min for 10 min, Rate up to 83%. In AcOH aqueous solution, Pd Ac2 / BQ (quinone) / Fe Pc catalyzed cyclopentene oxidation to cyclopentanone was more active than Pd Ac2 / Fe Pc, and the average oxygen uptake rates were 1.45 × 10 -2 mmol / min, 9.0 × 10 -3 mmol / mi
