摘　　要：设计并合成了一种新型配体１，２－二［６″－（６－甲基－４′－苯基－２，２′∶６′，２″－三联吡啶基）］乙烷。它是由１－（６′－甲基－２′－吡啶基）－３－苯基－２－丙烯－１－酮３与１－（６′－甲基－２′－吡啶基）－羰甲基吡啶碘盐４经改良的ＫｒＯｈｎｋｅ法先制得取代三联吡啶５，然后在氩气流中，－８０℃与ＬＤＡ、氧化剂１，２－二溴乙烷反应，偶联生成新化合物６。３、４、５、６的结构经元素分析、ＩＲ。A novel hexadentate ligand 1,2 bis[6″ (6 methyl 4′ phenyl 2,2′∶6′,2″ terpyridyl)]ethylene(6) in which two substituted terpyridine units is connected by an ethylene bridge has been synthesized by the reaction of substituted terpyridine(5) in the presence of Ar, at -80℃ with LDA and 1,2 dibromoethane. Using modified Krohnke method, 5 has been prepared by the reaction of 1 (6 methyl 2 pyridyl) 3 phenyl 2 propen 1 one(3) with 1 (6 methyl 2 pyridyl)carbonyl methyl pyridinium iodide(4). The structures of these new compounds 3, 4, 5, 6 have been confirmed by elemental analysis, IR, 1H NMR and MS.
