Development of Novel Recycling System for Organic Synthesis via Ionic Polymer-Gel

利用功能化聚合物提供的新型反应介质通常可以为试剂或催化剂回收系统的设计带来新的策略。我们已经开发了多相催化氧化系统利用离子聚丙烯酰胺为基础的聚合物凝胶。这些系统对几种使用清洁氧化剂的过渡金属催化氧化系统有效。此外，回收的催化剂可用于连续反应。并进一步探讨了该体系在富含槟糖羧酸的氧化卤代脱羧反应中的应用。

The use of a novel reaction medium provided by functionalized polymers could often bring a new strategy in the design of reagent or catalyst recycling systems. We have developed heterogeneous catalytic oxidation systems utilizing ionic polyacrylamide based polymer gel. These systems are effective for severaltransition metal-catalyzed oxidation systems using clean oxidants. In addition, the recovered catalyst could be used for consecutive reactions. Further applications of this system for oxidative halodecarboxylation of rich arenecarboxylic acids were also investigated.
