palladium(II)1-(arylazo)naphtholate complexes of the type [Pd(L1-4)2] containing sterically bulky O, N donor functionalized arylazo ligands has been synthesized. These palladium(II) complexes were characterized by elemental analysis and spectral (FT-IR, UV–Vis, 1H NMR and 13C NMR) studies. The molecular structure of the Palladium(II) complexes [Pd(L1)2] and [Pd(L2)2] were established by X-ray crystallography
合成了新型的[Pd(L 1-4)2 ]型钯(II)1-(芳基偶氮)萘甲酸酯络合物,其含有空间庞大的O,N供体官能化的芳基偶氮配体。这些钯(II)配合物的特征在于元素分析和光谱(FT-IR,UV-Vis,1 H NMR和13 C NMR)研究。通过X射线晶体学确定钯(II)配合物[Pd(L 1)2 ]和[Pd(L 2)2 ]的分子结构。发现这些络合物可有效催化DMF和i中芳基硼酸和芳基卤化物的Suzuki-Miyaura偶联以及芳基卤化物和苯乙炔的Sonogashira反应。-PrOH介质可提供高收率的相应C–C偶联产物。
