Structural Identification for Substituted Phenyl Pyrazoles and Isoxazoles by Nuclear Magnetic Resonance Spectroscopy |
| |
| Abstract: | 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. |
