5′-bi-1,2,4-triazine with benzenethiolate or 2-pyridinethiolate anion afforded the corresponding symmetrical disulfide of 5,5′-bi-1,2,4-triazine in high yields. These products were transformed into 6,6′-bis(phenylthio)-2,2′-bipyridines and 6,6′-bis(2-pyridylthio)-2,2′-bipyridines by using Diels-Alder reactions. All compounds were fully characterized by spectroscopic methods and the X-ray diffraction
摘要 3,3'-dichloro-5,5'-bi-1,2,4-triazine 中氯化物与苯硫醇或 2-pyridinethiolate 阴离子的亲核置换得到相应的对称二硫化物 5,5'-bi-1,2 ,4-三嗪收率高。通过使用Diels-Alder反应将这些产物转化为6,6'-双(苯硫基)-2,2'-联吡啶和6,6'-双(2-吡啶硫基)-2,2'-联吡啶。所有化合物都通过光谱方法和 X 射线衍射分析进行了充分表征。
