摘要：
Zinc in: Polyoxometalate 1 reacts with Zn2+ ions in acetone to form a novel sandwichtype POM 2 in almost quantitative yield. The H2O2-based oxidation of secondary alcohols with 2 efficiently proceeds, with an activity and chemoselectivity that is very different from those of tungsten-based catalysts including 1 (see scheme; green Zn). © 2010 Wiley-VCH Verlag GmbH & Co.
