4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C 3 H 5 )] 2 efficiently catalyses the Suzuki reaction of heteroarylboronic acids with aryl bromides and also the coupling of arylboronic acids with heteroaryl bromides. The coupling of thiopheneboronic acids. 3-furanboronic acid and 3-pyridineboronic acid with a variety of aryl bromides gave the corresponding adducts in good yields. However, in most cases,
cis,cis,cis-1,2,3,4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C 3 H 5 )] 2 有效催化杂芳基硼酸与芳基溴化物的 Suzuki 反应以及芳基硼酸与杂芳基的偶联溴化物。噻吩硼酸的偶联。3-呋喃硼酸和3-吡啶硼酸与各种芳基溴化物以良好的产率得到相应的加合物。然而,在大多数情况下,杂芳基溴化物与芳基硼酸的反应在底物/催化剂比方面获得了更好的结果。
