摘要：
PIPO, a readily prepared polymer immobilised TEMPO, is an efficient recyclable heterogeneous catalyst for the chlorinated hydrocarbon solvent- and bromide-free bleach oxidation of a variety of alcohols. Under these environmentally friendly conditions, PIPO is superior to homogeneous TEMPO and the previously described MCM-41 and silica supported TEMPO catalysts. In addition, in combination with CuCl, PIPO is also able to catalyse the aerobic oxidation of benzyl alcohol.
