the nucleophilic displacement of one of the chlorines from 2,4,6-trichloropyrimidine, we now report the initial displacement of one of the fluorine atoms from 2,4,6-trifluoropyrimidine using both aliphatic and aromatic amines. The monosubstitution products favor 2-substitution with ammonia and ethanolamine while aniline gave the 4-substituted derivative as the preferred product.
在我们继续进行涉及从2,4,6-三
氯嘧啶中置换一个
氯原子的研究的继续过程中,我们现在报告使用脂肪族和芳香族胺从2,4,6-三
氟嘧啶中置换一个
氟原子的初始方法。单取代产物有利于用
氨和
乙醇胺进行2-取代,而
苯胺给出了4-取代的衍
