چکیده
|
In this work, homogeneous and heterogeneous oxidation of alcohols by h2o2 in the presence of [(n-c4h9)4 n]5[pw11zno39].3h2o and [pw11zno39]5− supported on dowex 22 as catalysts have been investigated. using water as a green solvent, different alcohols were converted into the corresponding aldehydes and ketones in high to excellent yields. dowex 22 supported polyoxometalate, pw11zn@dowex, was also catalyzed highly robust and selective oxidation of unsaturated alcohols. leaching and recycling experiments on supported catalyst revealed the excellent stability and reusability of this catalytic system.
