From the results of Ru K-edge XAFS and XPS characterizations, MnFe1.5Ru0.35Cu0.15O4 catalyst with possibly coordinatively unsaturation of the isolated RuO species as active sites is an efficient heterogeneous catalyst and can be reused. Besides, the workup procedure is extremely simple.

The competition experiments clearly show that the rate-determining step of the reaction involves the generation of a partial positive charge in the benzylic position (i.e. hydride abstraction). This was further substantiated by the determination of a significant kinetic isotope effect (k H / k D = 1.41), when employing an alcohol substrate deuterated in this position.
