A selective and mild PS-DIB/ionic-liquid immobilized TEMPO 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 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 2,2,6,6-tetramethyl-piperidin-4-ol-N-oxyl and 1,4-dibromobutane.

将聚苯乙烯树脂先碘化再乙酰基化，制得了负载型二乙酰氧碘苯(diacetoxyiodo polystyrene，PS-DIB)作为氧化剂。2，2，6，6-四甲基-N-氧自由基哌啶醇(2，2，6，6-tetramethyl-piperidin-4-ol-N-oxyl，TEMPO)与1，4-二溴丁烷反应生成4-溴丁氧基-2，2，6，6-四甲基-哌啶-1-氧化物，再与N-甲基咪唑发生季铵化反应，生成的溴化季铵盐与四氟硼酸钠进行离子交换制得氟硼酸型2，2，6，6-四甲基-N-氧自由基哌啶负载离子液体TEMPO-IL。
