用线型聚苯乙烯负载二醋酸碘苯与对甲苯磺酸反应制得了聚苯乙烯负载羟基对甲苯磺酰氧基碘苯 ;该负载型高碘试剂作用与酮合成了α -对甲苯磺酰氧基酮 ,在此反应中显示出较好的反应活性 ,并且可循环使用 ,对环境友好
Polystyrene supported hydroxy p - toluenesulfonyloxyiodobenzene was obtained by the reaction of linear polystyrene supported iodobenzene diacetate with p - toluenesulfonic acid. The supported high iodine reagent synthesized α - p - toluenesulfonyl Oxyketones, which show good reactivity in this reaction, are recyclable and environmentally friendly
