and bis(pyridine) complexes and the influence of the pyridine ligand on the formation of these complexes. The catalytic activity of these complexes has been tested in the ring-closing metathesis (RCM) reaction of diallylmalononitrile and the cross metathesis (CM) reaction of acrylonitrile with terminal olefins.(© Wiley-VCH Verlag GmbH & Co.

带有 N-杂环卡宾 (NHC) 配体 1,3-双(2,6-二甲基苯基)-4,5-二氢咪唑-2-亚基 (H2IMe) 和一种或两种吡啶基配体的苄叉钌配合物已通过处理制备[RuCl2(=CHPh)(H2IMe)(PPh3)]与相应的吡啶衍生物。X 射线晶体学和质谱证据用于研究单和双(吡啶)配合物之间的相互转化以及吡啶配体对这些配合物形成的影响。这些配合物的催化活性已在二烯丙基丙二腈的闭环复分解 (RCM) 反应和丙烯腈与末端烯烃的交叉复分解 (CM) 反应中进行了测试。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim,德国,2007)
