Novel derivatives of Schiff bases with diazene bonds and six new 2,5-disubstituted pyrimidine derivatives were synthesized by reaction of 2-substituted trimethinium salts with 4-aminoazobenzene or benzamidine hydrochloride, respectively, by a simple method and using inexpensive reagents. The purity and molecular structure of the new compounds were determined by elemental analysis, mass spectrometry, infrared, ultraviolet/visible, as well as proton nuclear magnetic resonance (¹H NMR) and carbon-13 nuclear magnetic resonance (¹³C NMR) spectroscopy.

使用三甲铵盐合成新的席夫碱作为稳定的含烯醇亚胺的二氮烯键和嘧啶

通过 2-取代的三甲铵盐与 4-氨基偶氮苯或苯甲脒盐酸盐分别通过简单的方法和廉价的试剂反应合成了具有二氮烯键的新型席夫碱衍生物和六种新型 2,5-二取代嘧啶衍生物。通过元素分析、质谱、红外、紫外/可见光以及质子核磁共振（¹ H NMR）和碳13核磁共振（¹³ C NMR）光谱对新化合物的纯度和分子结构进行了测定。
