The bis(dihydrogen) complex RuH2(η2-H2)2(PCy3)2 (1) reacts with 2 equiv. of H2SiMePh to produce a mixture of Ru2H4(μ-η2:η2:η2:η2-SiH4)(PCy3)4 (2) and RuH2(η2-H2)(η2-HSiPh3)(PCy3)2 (4) together with HSiMePh2, HSiMe2Ph and traces of HMe2SiSiMe2H as a result of redistribution at silicon. The bridging SiH4 ligand in 2 is coordinated to the two ruthenium via four σ-Si–H bonds in agreement with NMR, X-ray
的双(二氢)络合物期RuH 2(η 2 -H 2)2(PCY 3)2 (1)反应与2当量 H的2 SiMePh,以产生由Ru组成的混合物2 ħ 4(μ-η 2:η 2:η 2:η 2 -SiH 4)(PCY 3)4 (2)和期RuH 2(η 2 -H 2)( η 2 -HSiPh 3)(PCY 3)2 (4)与HSiMePh 2,HSiMe 2 Ph以及痕量的HMe 2 SiSiMe 2 H一起在
硅上重新分布。桥接的SiH 4在
配体2配位的两个
钌经由4σ-SiH键与NMR,X射线数据协议(上2,和2 '的类似P我
镨3复合物)和DFT计算。每种相互作用都涉及对
钌的σ捐赠和与另一
钌的反向键合。消除SiH 4并形成RuH 2(CO)2(PCy 3)2 (5),期RuH 2(吨BuNC)2(PCY 3)2 (6)或期RuH(η 2 -H 2)
