以取代苄氯(1a~1c)为起始原料,与咪唑经氮烷基化反应制得苄基咪唑氯盐(2a~2c)；2a~2c与氧化银经原位去质子化反应合成了3种新型的氮杂环卡宾银配合物———(NHC)AgCl[NHC：1,3-二(4-甲氧基苄基)咪唑-2-亚基(3a),1,3-二(3-甲氧基苄基)咪唑-2-亚基(3b)]和[(NHC)AgCl]2[NHC=1,3-二(4-氯苄基)咪唑-2-亚基(3c)],其结构经1H NMR,13C NMR, IR,元素分析和X-射线单晶衍射表征。3a~3c单晶结构均属单斜晶系,3a为P21/n空间群,3b和3c为P21/c空间群,3a和3b为单核银配合物,3c为双核银配合物。“,”Benzyl imidazolium chlorides(2a~2c) were prepared by N-alkylation reaction of substitu-ted benzyl chloride with imidazole. Three novel silver N-heterocyclic carbene complexes, ( NHC) AgCl [NHC:1,3-bis(4-methoxybenzyl) imidazol-2-ylidene(3a), 1,3-bis(3-methoxybenzyl) imidazol-2-ylidene(3b)] and [(NHC)AgCl]2[NHC=1,3-bis(4-chlorobenzyl)imidazol-2-ylidene(3c)], were synthesized by the in situ deprotonation reaction of 2a~2c with Ag2 O. The structures were character-ized by 1 H NMR, 13 C NMR, IR, elemental analysis and X-ray single crystal diffraction analysis. 3a~3c belong to monoclinic crystal system, space groups are P21/n for 3a, P21/c for 3b and 3c. 3a and 3b are mononuclear Ag(I) complexes, where as 3c is a di-nuclear Ag(I) complex.
