摘　　要：以苯并咪唑、对甲基苯胺和氯乙酰氯为原料合成二(1-苯并咪唑基)甲烷和2-氯-N-(p-甲苯基)乙酰胺,并采用溶剂热法制备了一种新型酰胺官能化氮杂环卡宾钯配合物[(amide-NHC)Pd_(2)Cl_(4)]。通过PXRD、TGA、FT-IR和SCD对其进行表征。结果表明,目标配合物属于单斜晶系、P2_(1)/c空间群。将[(amide-NHC)Pd_(2)Cl_(4)]配合物应用于Suzuki-Miyaura偶联反应,当催化剂摩尔分数为2%时,催化产率高达98.74%。Using benzimidazole,p-methylaniline and chloroacetyl chloride as starting materials,Bis(1-benzimidazolyl)methane and 2-chloro-N-(p-tolyl)acetamide are obtained,and synthesized into a novel amide-functionalized nitrogen-heterocyclic-carbene(NHC)palladium complex[(amide-NHC)Pd_(2)Cl_(4)]by solvothermal method.It is characterized by means of PXRD,TGA,FT-IR and SCD.The results show that the complex belongs to a monoclinic crystal system,P2_(1)/c space group.The catalytic yield reaches as high as 98.74%when[(amide-NHC)Pd_(2)Cl_(4)]complex is applied for the Suzuki-Miyaura coupling reaction,with a dosage of only 2%.
