Phosphine functionalized imidazolium precursors were reacted with triiron(0)- resp. triruthenium(0)dodecacarbonyl in order to compare the reactivity of the Group VIII metals. Furthermore, [(η⁶-cymene)RuCl₂]₂ was treated in a transmetallation reaction with the silver(I) resp. copper(I) complexes of the corresponding imidazolylidenes possessing sterically largely different substituents at the NHC site, in order to evaluate the influence of these substituents on the catalytic activity of the ruthenium complexes.

[{2-（二苯基膦基苯基）甲基] -3-咪唑-2-基对第VIII族元素前体的反应性

将膦官能化的咪唑鎓前体与triiron（0）-resp反应。为了比较族金属的反应性，使用了三钌（0）十二碳羰基。此外，[（η ⁶ -cymene）的RuCl ₂ ] ₂是在与银（I）RESP一个金属转移反应处理。为了评估这些取代基对钌配合物催化活性的影响，相应的咪唑基亚甲基的铜（I）配合物在NHC位点具有空间上极大不同的取代基。
