reaction of heteroarylchlorides in the pyrimidine, pyrazine and quinazoline series with amines in water in the presence of KF results in a facile SNAr reaction and N‐arylation. The reaction is less satisfactory with pyridines unless an additional electron‐withdrawing group is present. The results showed that the transition‐metal‐free SNAr reaction not only compares favourably to palladium‐catalysed
嘧啶、吡嗪和喹唑啉系列中的杂芳基氯化物与水中的胺在 KF 存在下发生反应,导致容易的 S N Ar 反应和N芳基化。除非存在额外的吸电子基团,否则吡啶的反应不太令人满意。结果表明,无过渡金属的 S N Ar 反应不仅优于钯催化的偶联反应,而且在碱和溶剂方面也可以在环境可接受的(“绿色”)条件下进行。
