[reaction: see text] A new poly(ethylene glycol)-supported porphyrin has been prepared and its ability as a promoter in photooxidation reactions has been studied. The PEG-supported catalyst exhibits high activity, comparable to that of a nonanchored sensitizer, and it is easily removable by filtration from the reaction mixture. The polymer-bound porphyrin has been recycled up to six times with no loss of chemical and stereochemical efficiency.
[反应：见正文] 一种新的聚乙二醇负载卟啉已被制备出来，并对其作为光氧化反应促进剂的能力进行了研究。聚乙二醇负载的催化剂表现出高活性，与非固定化敏化剂相当，并且可以通过过滤轻松地从反应混合物中除去。聚合物结合的卟啉已循环使用多达六次，而化学和立体化学效率没有损失。
