Article abstract of DOI:10.1002/anie.201106064

Oxidation optimization: A combination of tungsten and zinc oxides on a SnO₂ support (W-Zn/SnO₂) is a heterogeneous and reusable solid catalyst for selective oxidation with aqueous H₂O₂. With it, various substrates, such as alkenes, amines, silanes, and sulfides, were oxidized into the corresponding products in high yields (see scheme). The catalyst can be reused several times without an appreciable loss in catalytic performance. Copyright
