were reacted in ethanol in harsh alkaline media provided by potassium hydroxide and after the work up the chemical yields of the reaction were calculated as 33.6%, 28.2% and 31.1% respectively. The synthesized compounds were characterized by 1H NMR, 13C NMR, FTIR and UVvisible spectroscopy. In addition, 1H and 13C NMR chemical shifts, IR and UV–vis spectrums were calculated theoretically in gas phase
在本研究中,通过羟醛缩合反应合成了三种不同的查耳酮化合物。4-羟基苯甲醛和酮化合物(苯乙酮、乙酰呋喃和硫代乙酰呋喃)在乙醇中由氢氧化钾提供的强碱性介质中反应,后处理后反应的化学产率分别计算为 33.6%、28.2% 和 31.1%。合成的化合物通过1 H NMR、13 C NMR、FTIR和紫外可见光谱表征。此外,1 H 和13通过使用B3LYP方法和6-311+g(d)基组,在气相中理论计算了C NMR化学位移、IR和UV-vis光谱,用于合成查耳酮的优化结构。实验获得的 FTIR 和 NMR 光谱表明目标分子是按要求合成的。从实验和理论上获得的所有数据都是相互兼容的。研究了Fe +3、Cd +2、Hg +2、Cu +2、Ni +2和Co +2金属离子的紫外-可见光谱,并研究了使用合成的这些查耳酮化合物是否可以检测金属。发现查尔酮3与Fe +3以外的五种金属离子(Cd +2、Hg +2、Cu
