[Ru3(CO)12] reacts at room temperature with N-alkyl substituted 6-membered ring N-heterocyclic carbenes (6-NHC) to form [Ru3(6-NHC)(CO)10] (6-NHC = 6-iPr 1, 6-Et 2 and 6-Me 4), rare examples of coordinatively unsaturated (46-electron) ruthenium clusters. Complexes 1, 2 and 4 have been structurally characterised, along with the tetranuclear ruthenium cluster [Ru4(6-Et)2(CO)11] 3 that is formed along
[Ru 3(CO)12 ]在室温下与N烷基取代的6元环N-杂环卡宾(6-NHC)反应,形成[Ru 3(6-NHC)(CO)10 ](6-NHC = 6-我镨1,6-ET 2和6-ME 4),配位不饱和(46-电子)合钌簇的罕见例子。配合物1,2和4已经被结构表征,用四核钌簇沿的[Ru 4(6-ET)2(CO)11 ] 3,其与沿形成2。通过嘧啶鎓盐消除对6- i Pr衍生物1的降解有助于解释该络合物在吡啶的催化酰化中的活性差。
