摘　　要：以2-氯乙胺缩水杨醛和正丁基咪唑为原料合成席夫碱官能化氮杂环卡宾配体,以合成的配体为原料,三(三环己基膦)二氯化钌为前体,采用溶剂热法合成有机膦配体的银金属配合物。利用X射线单晶衍射、X射线粉末衍射、红外光谱等进行结构表征,结果表明银金属配合物属于正交晶系,Pcnb空间群,中心原子Ag为四配位。将有机膦配体银金属配合物应用于催化Suzuki-Miyaura交叉偶联反应中,结果表明,以溴苯和苯硼酸为底物,K_(2)CO_(3)为助催化剂,乙醇为溶剂,n(催化剂)=0.02 mmol、t=90℃、t=8 h,联苯的产率为78.64%。The Schiff base-functionalized N-heterocyclic carbene ligand was synthesized using 2-chloroethylamine salicylaldehyde and n-butylimidazole as raw materials.Then,taking the synthesized ligand as the raw material and tris(tricyclohexylphosphine)ruthenium dichloride as the precursor,the silver metal complex of the organophosphorus ligand was synthesized by the solvothermal method.The structure was characterized by X-ray single crystal diffraction analysis,X-ray powder diffraction analysis and infrared spectroscopy analysis.The results showed that the silver complex belonged to the orthorhombic crystal system,with the Pcnb space group,and the central atom Ag was four-coordinated.The silver complex of the organophosphorus ligand was applied to the catalytic Suzuki-Miyaura coupling reaction.The catalytic results showed that the yield of biphenyl reached 78.64%when bromobenzene and phenylboric acid were used as substrates,potassium carbonate as co-catalyst,ethanol as solvents,and catalysts of 0.02 mmol at 90℃for 8 h.
