设计了由1,3-二(2,6-二甲基苯基)-2-四氢咪唑基-苯亚甲基-三苯基膦-二氯合钌(7)和吡啶反应生成无膦型金属钌卡宾化合物1,3-二(2,6-二甲苯基)-2-四氢咪唑基-苯亚甲基-2-吡啶基-二氯合钌(8), 8作为高效催化剂用于丙烯腈和烯丙基苯的交叉交互置换反应. 新化合物7, 8经核磁共振氢谱、碳谱和高分辨率质谱予以证实.

关键词: 制备, 钌, 交互置换

The free-phosphine carbene ruthenium complex [1,3-bis(2,6-dimethylphenyl)-2-tetrahydroimi- da-zol](C5H5N)2(Cl)2Ru＝CHPh (8) was pre-pared by the reaction of [1,3-bis(2,6-dimethylphenyl)-2-tetra-hydroimidazol](PPh3)(Cl)2Ru＝CHPh (7) with pyridine and used as a highly effective catalyst for the cross metathesis of acrylonitrile with allylbenzene. The structures of new compounds 7 and 8 were identified by 1H NMR, 13C NMR and HRMS spectra.

Key words: synthesis, metathesis, ruthenium
