The highly efficient aerobic oxidation of alcohols to carbonyl compounds was achieved catalyzed by cationic meso-tetrakis (1-methyl-4-pyridyl, TM4PyP) metalloporphyrins immobilized in montmorillonite interlayers. Cobalt porphyrin (CoTM4PyP-MT) showed excellent activity and selectivity in the aerobic oxidation of benzyl alcohol, where 90% yield of benzaldehyde was obtained. CoTM4PyP-MT can be five times reused without significant loss of activity.
摘要制备了蒙脱土负载的离子型四 (1-甲基-4-吡啶基) 金属卟啉, 并用于催化醇类氧化制备羰基化合物的反应中. 结果表明, 该催化剂表现出优异的活性和产物选择性, 其中在苯甲醇氧化反应中, 苯甲醛收率可达 90%, 且连续重复使用 5 次后, 其活性未见明显下降.
Efficient aerobic oxidation of alcohols catalyzed by cobalt porphyrin immobilized into montmorillonite was achieved. The catalyst could be five times consecutively reused.Figure optionsDownload as PowerPoint slide
