聚合物支载的苄硒醇与端位环氧化物反应研究

Study on the Reactions of Polymer - supported Benzyl Selenol With Terminal Epokides

为了深入研究聚合物支载苄硒醇的性质，我们制备了苯乙烯／二乙烯基苯共聚物支载的苄硒醇ＣＨ２ＳｅＨ，１，它经ＮａＢＨ４还原后与端位环氧化物反应生成载体的β－羟基硒醚，用３０％Ｈ２Ｏ２氧化后，得到相应的２－酮，提供了一个制备２－酮的新方法，并对反应机理进行了探讨．

In order to study foe features of polymer - supported selenol, Prepared the benzyl selenol supportedby copolymer of vinyl benzene/divinyl benzene. It reacted with tenonal epotides giving supported selenides with β- OH respectively, which were oaldised by 30 % H2O2 to Produce 2 - ketones. The reaction mechanism was proposed.
