Composites of [ﾎｳ-H2PV2W10O40]3- and [ﾎｱ-SiW12O40]4- supported on Fe2O3 as heterogeneous catalysts for selective oxidation with aqueous hydrogen peroxide.
Composites of [ﾎｳ-H2PV2W10O40]3- and [ﾎｱ-SiW12O40]4- supported on Fe2O3 (PV2-SiW12/Fe2O3, in particular, the molar ratio of PV2/SiW12 = 1/1) could act as effective and reusable heterogeneous catalysts for selective oxidn. with aq. hydrogen peroxide. In the presence of PV2-SiW12/Fe2O3, various kinds of org. substrates such as alkenes, sulfides, arenes, and alkanes could selectively be converted into the corresponding oxygenated products in moderate to high yields. The obsd. catalyzes for the present oxidns. were intrinsically heterogeneous, and PV2-SiW12/Fe2O3 could be reused at least three times for each oxidn. (epoxidn., sulfoxidn., and arene hydroxylation) without appreciable losses of the high catalytic performance. [on SciFinder(R)]
