本文测定了1-(3—吡啶甲酰)—4—苯基氨基硫脲、3—(3—吡啶基)—4—苯基—1,2,4—三唑啉—5—硫酮等8个新化合物的~(13)C NMR谱,运用质子宽带去偶、偏共振去偶,结合信号强度对比、苯基取代基效应的计算,同时与模型化合物对照,一一归属了其谱峰。本文对这两类化合物之间的~(13)C NMR谱差异进行了探讨,并得到了在吡啶环3位取代的甲酰肼基对吡啶环各碳取代基效应的数据。 In this paper, the effects of 1- (3-pyridinecarboxyl) -4-phenylthiosemicarbazone, 3- (3-pyridyl) -4-phenyl-1,2,4-triazoline-5-thione and the like The ~ (13) C NMR spectra of eight new compounds were calculated by broadband proton depolarization, partial resonance depolarization, the combination of signal intensities and the calculation of the effect of phenyl substituents. At the same time, . In this paper, the differences of ~ (13) C NMR spectra between the two compounds were discussed, and the effect of carbonyl hydrazide groups substituted at the 3-position on the pyridine ring on the carbon substituents on the pyridine ring was obtained.
