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-取代的衍生物作为优选产物。
