efficient, and recyclable bifunctional catalysts bearing ionic liquid supported (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) and iodoarene moieties were developed and used for environmentally benign catalytic oxidation of alcohols. The reactions using peracetic acid as a green and practical co-oxidant afforded the corresponding carbonyl compounds in high yields under mild conditions and convenient work-up
开发了带有离子液体负载的(2,2,6,6-四甲基哌啶-1-基)氧基(TEMPO)和碘芳烃基团的新型,高效且可回收的双功能催化剂,并将其用于环境友好的醇催化氧化。使用过氧乙酸作为绿色和实用的助氧化剂的反应在温和的条件下和方便的后处理下以高收率提供了相应的羰基化合物。此外,这些离子液体负载的双官能催化剂可以简单地回收和再利用。
