双腈氯化钯的制备、结构表征及催化活性评价

Synthesis,characterization and catalytic activity of bis(nitrile)dichloropalladium(Ⅱ)

摘要: 以二氯化钯为起始原料,在比较温和的反应条件下制备了双(乙腈)二氯合钯和双(苯腈)二氯合钯,产率97％.采用元素分析、1H NMR、13C NMR和 IR对其化学结构进行了表征,并以Suzuki C-C偶联反应为模型评价了其催化活性,催化转化率70%～88%.

Abstract: Two palladium(Ⅱ) homogeneous catalysts for the Suzuki coupling reactions,bis(acetonitrile)dichloropalladium and bis(benzonitrile)dichloropalladium,were synthesized in a yield of 97% from palladium chloride as the raw material.The structures were confirmed by means of elemental analysis,1H NMR,13C NMR and FT-IR.The catalytic activity of both complexes in a Suzuki coupling reaction was found to be 70%88% in terms of the conversion rate.
