ABSTRACT In this article, direct N-alkylation of secondary amines with carboxylic acid is described. Readily available diversified carboxylic acid has been explored on variant secondary amines using encapsulated Nickel as catalyst and inexpensive sodium borohydride as the hydride source. High yields, mild reaction conditions, tolerance to sensitive functional group and facile operational procedure
摘要 在本文中,描述了仲胺与羧酸的直接 N-烷基化反应。已经使用包封的镍作为催化剂和廉价的硼氢化钠作为氢化物源,在变体仲胺上探索了容易获得的多样化羧酸。高产率、温和的反应条件、对敏感官能团的耐受性和简便的操作程序是本方法的重要意义。图形概要
