[reaction: see text] Attachment of poly(ethylene glycol) (PEG) to ruthenium porphyrin via a covalent etheric bond gives soluble polymer-supported ruthenium catalysts 3-5. These catalysts exhibit high reactivity and selectivity toward alkene epoxidation with 2,6-dichloropyridine N-oxide and alkene cyclopropanation with diazo compounds. The application of these catalysts in the synthesis of unstable
[反应:见正文]聚乙二醇(PEG)通过共价醚键连接到钌卟啉上,得到了可溶性聚合物负载的钌催化剂3-5。这些催化剂对用2,6-二氯吡啶N-氧化物进行的烯烃环氧化和用重氮化合物进行的烯烃环丙烷化表现出高反应性和选择性。已经证明了这些催化剂在不稳定有机化合物的合成中的应用。
