蒙脱土负载钴卟啉：一种在催化醇类氧化制备羰基化合物中可循环使用的高效催化剂(英文)

Cobalt Porphyrin Immobilized on Montmorillonite:A Highly Efficient and Reusable Catalyst for Aerobic Oxidation of Alcohols to Carbonyl Compounds

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.

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.
