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)

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%.

Two palladium （ Ⅱ ） homogeneous catalysts for the Suzuki coupling reactions, bis （ chloropalladium and bis （benzonitrile）dichloropalladium, were synthesized in a yield of 97% acetonitrile） di- from palladium chloride as the raw material. The structures were confirmed by means of elemental analysis, 1H NMR, 13C 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.
