开发了一种一步合成聚硒醚的新方法,该材料可用于催化环己烯二羟化合成重要的化工中间体环己二醇,是一种高效并可回收的催化剂.有趣的是,该材料在分子层面的独特结构,使得相关反应以自由基机理进行,并可使用分子氧作为部分氧化剂,这与之前许多报道的硒催化反应有所不同.“,”A new method for one-step synthesis of polyselenide was developed.The material was found to be an efficient and recyclable catalyst for the dihydroxylation of cyclohexene to produce 1,2-cyclohexanediol,which was an important inter-mediate for the synthesis of many fine chemicals.Interestingly,the unique structure of the catalyst at molecular level resulted in a novel free-radical reaction methanism allowing the utilization of O2 as the supplementary oxidant,which was quite different from most of the reported organoselenium-catalyzed reactions.
