【摘要】 苯并咪唑与碘苯在Cu I催化下经取代反应制得1,2-二苯基苯并咪唑(L);L与K2Pt Cl4在乙二醇单乙醚和水中经配位反应合成了两个新型的1,2-二苯基苯并咪唑铂(Ⅱ)配合物——L2Pt Cl(1)和L2Pt Cl2(2),其结构经1H NMR和X-射线单晶衍射表征。1的UV-Vis光谱显示明显的金属到配体的电荷转移跃迁,λmax位于238nm,279 nm,300 nm,315 nm和360 nm;2的λmax位于237 nm和285 nm。更多还原

【Abstract】 1,2-Diphenyl-benzoimidazole( L) was prepared by substitution reaction of benzimidazole with iodo-benzene catalyzed by Cu I. Two novel Pt( Ⅱ) complexes,L2 Pt Cl( 1) and L2 Pt Cl2( 2),were synthesized by coordination reaction of L with K2 Pt Cl4in 2-ethoxyethanol / H2 O solution. The structures were characterized by1 H NMR and X-ray single crystal diffraction. UV-Vis spectrum of 1exhibited a classical metal-to-ligand charge transfer transition,λmaxwere 238 nm,279 nm,300 nm,315 nm and 360 nm. λmaxof 2 were 237 nm and 285 nm.更多还原
