将四个乙烯基功能化的手性钌卟啉配合物与苯乙烯、二乙烯基苯（或乙二醇二甲基丙烯酸酯）进行聚合，得到了负载型钌配合物。以这些聚合物为催化剂，进行了重氮乙酸乙酯（或重氮乙腈）与苯乙烯衍生物的不对称加成反应。反应在温和的条件下进行，并得到具有良好的对映体过量（高达90%）的反式环丙烷。(c)2005爱思唯尔有限公司保留所有权利。
A chiral ruthenium porphyrin complex, functionalized with four vinyl groups, has been polymerized with styrene, divinylbenzene (or ethylene glycol dimethacrylate) to obtain supported ruthenium complexes. The asymmetric addition of ethyl diazoacetate (or diazoacetonitrile) to styrene derivatives was carried out by using these polymers as catalysts. The reaction proceeded under mild conditions and gave trans-cyclopropanes with good enantiomeric excess (up to 90%). (c) 2005 Elsevier Ltd. All rights reserved.
