A series of new 4-(3,5-disubstitue-4H-1,2,4-triazol-4-yl)- 5-(thiophen-2-yl-methyl)-2H-1,2,4-triazol-3(4H)-ones (3a-c) were obtained by reaction N'-1-ethoxy-2-thiophen-2-yl-ethylydene hydrazino carbox...
铜离子催化DPKA关环反应及其潜在应用(CuⅡ-induced Ring-formation Reaction of Di-pyridylketone Azine and Its Potential Application)
二吡啶酮肼合物 离子识别 荧光 铜离子
2010/8/18
铜离子催化的氧化关环有机反应,用于选择性荧光探测金属铜离子的存在。晶体结构和光谱分析表明,在DPKA的乙腈/水混合溶剂中,引入铜离子可以促使苯并三氮唑类荧光化合物(2)的形成,该反应可以使得溶液的荧光明显增强。而且在滴定溶液里,引入Cu2+螯合剂EDTA,并不能使得溶液的荧光减弱,表明荧光是由有机物2发射的。同时,其他金属离子的引入并不能产生荧光,而且干扰离子的存在也不能使得荧光光谱发生显著改变,...
