Monoalkylation of primary amines using amine hydrobromides and alkyl bromides has been carried out. Under controlled reaction conditions the reactant primary amine was selectively deprotonated and made available for reaction, while the newly generated secondary amine remained protonated, and did not participate in alkylation further. Reaction was carried out under mild reaction conditions and was applicable to a wide range of primary amines and alkyl bromides.
使用胺
溴化物和卤代烷对初级胺进行单烷基化已成功实现。在受控反应条件下,反应物初级胺被选择性去质子化,从而可供反应,而新生成的次级胺保持质子化状态,未进一步参与烷基化反应。反应在温和的条件下进行,并适用于多种初级胺和卤代烷。
