Two transition-metal-modified Nb/W mixed-addendum polyoxometalates for visible-light-mediated aerobic benzylic C-H oxidations
文献摘要：
The visible-light-induced selective oxidation of ubiquitous C-H bonds into valuable C=O bonds under aerobic conditions is one of the most attractive approaches for the construction of carbonyl-containing molecules.In this work,two transition metal-containing Nb/W mixed-addendum POMs dimers with the formula of K2Na2H5[(Fe(H2O)4)3(P2W15Nb3O62)2]·24H2O(POM[Fe])and K2Na3H4[(Cr(H2O)4)3(P2W15Nb3O62)2]·32H2O(POM[Cr])have been synthesized and characterized by var-ious analytical and spectral techniques.POM[Fe]was proved to be an efficient photocatalyst for benzylic C-H oxidation under visible light and using oxygen as an oxidant to produce the corresponding carbonyl complex in good yields.A plausible mechanism involving superoxide radical was proposed for the cat-alytic reaction.POM[Fe]showed good reusability in the recycling experiments.IR spectroscopy and XRD analysis indicate that POM[Fe]can retain its integrity after catalysis.
