A convenient and general method for Suzuki–Miyaura double cross-coupling of various dibromothiophenes was developed. Using a simple and cheap catalytic system Pd(OAc)2/PPh3 in 95% EtOH, various (hetero)arylboronic acids react with dibromothiophenes providing diarylthiophenes, useful in the synthesis of metal–organic frameworks (MOFs), in moderate to excellent yields. The overall efficiency of the catalytic
开发了一种方便和通用的各种二溴噻吩的 Suzuki-Miyaura 双交叉偶联方法。在 95% EtOH 中使用简单且廉价的催化体系 Pd(OAc) 2 /PPh 3,各种(杂)芳基硼酸与二溴噻吩反应提供二芳基噻吩,可用于合成金属有机骨架(MOF),产率适中. 催化过程的整体效率和略微过量的硼酸可以抑制副产物的形成并显着简化产物的纯化。
