N‐alkylation reaction of aromatic amines was achieved using aliphatic, aromatic, and heteroaromatic alcohols as the alkylating reagent. A variety of aniline derivatives, including heteroaromatic amines, underwent the N‐alkylation reaction and furnished the corresponding monoalkylated products in good to excellent yields. The application of the reaction is also further demonstrated by the synthesis of a 2‐phenylquinoline
使用脂肪族,芳香族和杂芳香族醇作为烷基化试剂,可以实现锌的芳香胺的N烷基化反应。各种杂苯胺衍生物,包括杂芳族胺,都经过了N-烷基化反应,并以良好的产率提供了相应的单烷基化产物。由苯乙酮和2-氨基苄醇合成2-苯基喹啉衍生物也进一步证明了该反应的应用。氘标记实验表明,反应是通过借用氢过程进行的。
