摘要 用1 H ,1 3CNMR和多种二维核磁共振谱表征了本系列化合物的结构 ,完成了1 H和1 3CNMR谱带的归属 ,测定了氟原子对各质子和碳原子的偶合常数 ,探讨了影响偶合常数大小的因素。 The structures of the title compounds were identified by 1H, 13 C and various two dimensional nuclear magnetic resonance (NNR) spectra with all absorptions of 1H and 13 C NMR assigned. The coupling constants between 19 F and 1H/ 13 C were determined accurately. The factors affecting coupling constant values have been investigated.
