Two Copper-Containing Polyoxometalate-Based Metal–Organic Complexes as Heterogeneous Catalysts for the C–H Bond Oxidation of Benzylic Compounds and Olefin Epoxidation

-Cu-pbba catalyzed the oxidation of indane into 1-indanone with an 81% yield and >99% selectivity within 48 h. As heterogeneous catalysts, both complexes demonstrated excellent recoverability and high stability and could be stably reused five times without significant activity loss.
