| 中文摘要: |
| 以1,1’-双(二苯基膦)二茂铁(dppf)、1,1’-双(二叔丁基膦)二茂铁(dtbpf)为配体，合成了一类双齿有机膦二茂铁钯(II)配合物[(dppf)PdCl2]、[(dtbpf)PdCl2] 、[(dppf)PdBr2]和[(dtbpf)PdBr2]，通过核磁共振对配合物进行化学结构表征。评价了它们对Suzuki偶联反应、Sonogashira偶联反应、Heck偶联反应以及2-羟基吡啶与硼酸试剂之间的偶联反应的催化作用。结果表明，配合物化学性质稳定，在非保护气氛下能高效地催化一系列偶联反应。催化剂在单边Sonogashira偶联反应中不但具有较高的催化活性，而且有很好的选择性，显示出很好的应用前景。 |
| 英文摘要: |
| Four palladium(II) complexes of organic bidentate phosphine ferrocene, [(dppf)PdCl2], [(dtbpf)PdCl2], [(dppf)PdBr2], [(dtbpf)PdBr2], were prepared via a direct reaction in an inert atmosphere using Na2PdX4 (X=Cl, Br) as the palladium precursor and the corresponding phosphine ferrocene as the ligand (dppf=1,1’-bis(dipheny-phosphino)ferrocene, dtbpf=1,1’-bis(di-tert-butylphosphino) ferrocene). The complexes were characterized by 1H NMR. The catalytic performance of the complexes was evaluated not only in three well-kunown coupling reactions (Suzuki, Sonogashira and Heck coupling reaction) but also in the coupling reaction between 2-hydroxypyridine and boronic acid reagent. The results showed that the complexes are stable and can efficiently catalyze a series of coupling reactions in a non-protective atmosphere. The catalyst not only has high catalytic activity in unilateral Sonogashira coupling reaction, but also has good selectivity, showing a good application prospect. |
