ABSTRACT A protocol that carboxylic acids esterifies with the quaternary ammonium salt of deep eutectic solvent (DES) is presented, which opens a new access to ester using DES as alkylating agent, solvent, and catalyst. The reaction runs smoothly in DES without any other additives. Substituted cinnamic acids, aromatic acids, and aliphatic acids can be esterified in moderate to good yields. The advantages
摘要提出了一种羧酸与深共熔溶剂 (DES) 的季铵盐进行酯化的协议,它开辟了使用 DES 作为烷化剂、溶剂和催化剂获得酯的新途径。反应在 DES 中顺利进行,无需任何其他添加剂。取代的肉桂酸、芳香酸和脂肪酸可以以中等至良好的收率进行酯化。该反应的优点是官能团相容性好,反应过程简单。图形概要
