Abstract A rapid and efficient diesterification reaction of aromatic carboxylate with 1,4-dibromobutane was carried out in water at 100 °C in the presence of base and phase transfer catalyst under focused microwave irradiation. This microwave-promoted protocol offers an atom-efficient and environment-friendly approach to synthesize butamethylenediesters in high yield. Graphical Abstract
摘要 在碱和相转移催化剂的存在下,在聚焦微波辐射下,在100 °C 的水中,芳族羧酸酯与1,4-二溴丁烷的二酯化反应快速有效地进行。这种微波促进的协议提供了一种原子效率高且环境友好的方法来合成高产率的丁亚甲基二酯。图形概要
