摘要: 本文测定了新合成的,具有生理活性的1-(4-吡啶甲酰)-4-苯基氨基硫脲,1-(4-吡啶甲酰)-4-对氯苯基氨基硫脲,1-(4-吡啶甲酰)-4-对溴苯基氨基硫脲3-(4-吡啶基)-4-苯基-1,2,4,-三唑啉-5-硫酮,3-(4-吡啶基)-4-对氯苯基-1,2,4,-三唑啉-5-硫酮,3-(4-吡啶基)-4-对溴苯基-1,2,4-三唑啉-5-硫酮六个新化合物的13C-NMR谱,并通过13C-NMR谱中的宽带去偶,偏共振及APT技术,模型化合物对照,讯号强度对比及芳基取代基常数计算等方法,进行了上述化合物13C-NMR谱峰的归属,并得到了甲酰肼基在吡啶环4位取代后对吡啶环各碳所产生的取代基效应.

Abstract: The carbon-13 NMR spectra of 1-(4-pyridine acyl)-4-phenyl thioscmicarbazide, 1-(4-pyridine acyl)-4-p-chlorO-phenylthiosemicarbazide, 1-(4-pyridine acyl)-4-p-bromo-phenylthiosemicarba/ide, 3-(4-pyridinyl)-4-phenyl-1, 2, 4-triazoline-5-thionc, 3-(4-pyridinyl)-p-chloro phenyl-1, 2, 4-triazoline-5-thione, 3-(4-pyridinyl)-p-bromo phenyl-1, 2, 4-triazoline-5-thione and their derivatives were studied in this paper. The chemical shifts of various carbon resonance peaks were assigned by the proton-noise decoupling, Off-resonance, APT-technique, and use of empirical methods. At the same time, the substituent effects of 4-hydrazide in monosubstituted pyridinc were obtained. These parameters are Z42 (Z46) 0.1ppm Z43 (Z45)-3.3ppm and Z44 3.9ppm (solvent:polysol; reference:TMS).

Key words: The effect of substituent, 13C-NMR
