A new class of palladium(II)1-(arylazo)naphtholate complexes of the type [Pd(L_1-4)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. These complexes were found to efficiently catalyze the Suzuki-Miyaura coupling of arylboronic acids and aryl halides, and the Sonogashira reaction of aryl halides and phenylacetylene in DMF and i-PrOH media to afford the corresponding C–C coupling products in high yields.

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。
