我们报道了两个膦基咪唑衍生的双钯配合物在钯催化的胺化反应中的催化活性。我们的研究表明,二聚体络合物的起始氧化态(Pd(I)或Pd(II))对催化反应的效率具有显著影响。相应的Pd(I)配合物在Buchwald-Hartwig胺化反应中表现出更高的反应性,而Pd(II)配合物在羰基化胺化反应中表现出更高的反应性。这些新的二聚钯络合物在所测试的胺化反应中提供良好至优异的反应性和产率。
We report the catalytic activity of two phosphinoimidazole-derived bimetallic palladium complexes in Pd-catalyzed amination reactions. Our studies demonstrate that the starting oxidation state (Pd(I) or Pd(II)) of the dimeric complex has a significant effect on the efficiency of the catalytic reaction. The corresponding Pd(I) complex shows higher reactivity in Buchwald–Hartwig aminations, while the Pd(II) complex is much more reactive in carbonylative amination reactions. These new dimeric palladium complexes provide good to excellent reactivity and yields in the amination reactions tested.
