A selective and mild PS-DIB/ionic-liquid immobilized 2, 2, 6, 6-tetramethyl-piperidin-4-ol-N-oxyl catalytic oxidation procedure of alcohols to the corresponding aldehydes and ketones in ionic liquid BF4 at room temperature was developed. The oxidant PS-DIB was prepared via the iodation and acetylation of polystyrene resin. For the preparation of the ionic-liquid immobilized TeMPO catalyst, 4-(2, 2, 6, 6-Tetramethyl-1-oxyl-4-piperidoxyl)butyl bromide was first synthesized from TeMPO and 1, 4-dibromobutane.
