ne/[PdCl(C3H5)]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 thiophene- or benzothiopheneboronic acids, furan- or benzofuranboronic acids and 3-pyridineboronic acid with a variety of aryl bromides gave the corresponding coupling products in good yields. However, in most cases
顺式,顺式,顺式-1,2,3,4-四(二苯基膦甲基)环戊烷/ [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。噻吩或苯并噻吩硼酸,呋喃或苯并呋喃硼酸和3-吡啶硼酸与各种芳基溴的偶合得到相应的偶合产物,收率很高。然而,在大多数情况下,使用杂芳基溴化物与芳基硼酸进行的逆反应在底物/催化剂的比例方面获得了更好的结果。
