摘要
研究了卤代苯和卤代萘磺化产物的1HNMR分析方法.结合各产物有关质子的化学位移.偶合常数.分裂形式.积分高度可得到各种磺化产物的比例.讨论了双共振去偶合实验的具体应用,化学位移理论值的计算及其在质子谱峰归属中所起的作用,磺化产物1H和19F的偶合分裂现象.首次报道了卤代芳香化合物多磺酸取代产物的1HNMR数值.
H NMR study on the reaction products of sulfur trioxide with four halobenzenes, six halonaphthalenes is reported. The chemical shifts of sulfo derivatives have been assigned. The 1H NMR data of disulfo and trisulfo derivatives of halobenzenes and halonaphthalenes have been reported for the first time. The application of double resonance, coupling constant of 1H and 19F, calculation data of chemical shift were also discussed.
