  一种6,6`-二取代-3,3`,4,4`-联苯四甲酸及其二酐与其制备方法

  摘要：

  本发明公开了一种6,6'‑二取代‑3,3',4,4'‑联苯四甲酸及其二酐与其制备方法，所述6,6'‑二取代‑3,3',4,4'‑联苯四甲酸及其二酐的结构分别如式(I)和式(II)所示，R选自烃基、烃氧基、取代烃基或取代烃氧基，在同一结构式中的两个R相同或不同；#imgabs0#所述制备方法在季铵盐存在下、采用卤素卤代制备4‑卤代‑5‑取代邻苯二甲酸，随后在可见光照条件下进行钯催化偶联，可将4‑卤代‑5‑取代邻苯二甲酸直接偶联生成6,6'‑二取代‑3,3',4,4'‑联苯四甲酸，进一步脱水即可获得相应二酐。本发明避免了现有技术中使用浓硫酸作为辅助试剂进行溴化的方法，反应条件温和。
