Synthesis of novel magnetic silica supported hybrid ionic liquid combining TEMPO and polyoxometalate and its application for selective oxidation of alcohols

A novel magnetic silica supported bifunctional hybrid material (IL/SMNP) combining TEMPO based ionic liquid and polyoxometalate moieties was developed and used in the selective aerobic oxidation of various alcohols. A pseudo-homogeneous and environmental benign process was achieved with excellent activity and easy recovery of the catalyst.
