products 4 and 5, the latter predominating with higher CS2 concentration. The NMR spectra and an X-ray analysis of 4 clarified the structures. The hinderedrotation about the CN bond of the N,N-diethylthiocarboxamide groups is responsible for the temperature-dependent dynamic processes observed in the 1H NMR spectra of 4 and 5. In analogy with the known reaction of the ynamine 3 with CO2, the thi
环加合物1与异喹啉鎓N-苯基酰亚胺(2)和CS 2处于流动平衡状态。的反应1与1-(二乙基氨基)丙炔(3:1:1级的产品,得到1)4和5,后者者为主具有较高的CS 2的浓度。NMR谱和的X射线分析4阐明了结构。N,N-二乙基硫代羧酰胺基团绕CN键的旋转受阻是4在1 H NMR光谱中观察到的温度依赖性动态过程的原因和5。与已知的氨基胺3与CO 2的反应相似,假定硫代氨基甲酰基-硫代乙烯酮11为关键中间体,其在CC或CS键处接受1,3-偶极。ynamine的反应3与CS 2在没有2在适度的产率2产品:提供一个2。
