Immobilization of Ru(terpyridine)(2,6-pyridinedicarboxylate) onto MCM-41 and its.

The ruthenium complex Ru(terpyridine)(2,6-pyridinedicarboxylate) was successfully grafted onto MCM-41 using a multi-step grafting method. The immobilized ruthenium complex was characterized thoroughly using Fourier transform infrared, Raman, UV-visible and energy-dispersive X-ray spectroscopies, X-ray diffraction, N2 adsorption, scanning , thermogravimetric analysis and analysis. This immobilized ruthenium complex showed excellent performance in the oxidation of various secondary alcohols to their corresponding ketones with tert-butyl hydroperoxide as oxidant under solvent-free conditions, and had the advantages of easy recovery and good reusability.
