of polystyrene-supported (dichloroiodo)benzene (loading of -ICl2 up to 1.35 mmol/g) from polystyrene, iodine, and bleach has been developed. This recyclable reagent is useful for efficient chlorination of organic substrates and selective oxidation of various alcohols to the corresponding carbonyl compounds in high yields under mild conditions. The final products are conveniently separated from the polymeric
已经开发了一种由聚苯乙烯,碘和漂白剂制备的方便的一锅法制备的聚苯乙烯负载的(二氯碘代)苯(-ICl 2的负载量高达1.35 mmol / g)。这种可循环使用的试剂可用于在温和条件下以高收率将有机底物有效氯化,并将各种醇选择性氧化为相应的羰基化合物。通过简单的过滤将最终产物方便地与聚合物副产物分离,并在蒸发溶剂后以良好的纯度分离出最终产物。
