  • Clean and selective oxidation of alcohols catalyzed by ion-supported TEMPO in water
    作者:Weixing Qian、Erlei Jin、Weiliang Bao、Yongmin Zhang

    日期:2006.1
    chemoselective oxidation of alcohols is investigated. These new catalysts show high catalytic activity in water and can be reused for the next run by extraction of products. Recycling experiments exhibit that ion-supported TEMPO can be reused up to five times without loss of catalytic activity. This system offers a very clean, convenient, environmentally benign method for the selective oxidation of alcohols

Moreover, the reaction rate is greatly enhanced when a proper amount of water is present. And a high turnover number (TON 5000) is achieved in the present transition metal-free aerobic catalytic system. Additionally, the functionalized
