The reactions of the ruthenium hydride complexes [{Ru(COD)(H)(NH2NMe2)3}{BArF}] (BArF=B{C6H3(CF3)2}4), [{CpRu}2(micro-H)4] and [{CpRu}3(micro-H)3(micro3-H)2] with GaCp* and AlCp* are investigated. The reaction of [{Ru(COD)(H)(NH2NMe2)3}{BArF}] with GaCp* leads to substitution of the hydrazine ligands by GaCp* and the formation of [{Ru(COD)(H)(GaCp*)3}{BArF}] (), while the reactions of [{CpRu}2(micro-H)4] and [{CpRu}3(micro-H)3(micro3-H)2] with ECp* (E=Al, Ga) results in the formation of the polyhydride clusters [{CpRu(micro-H)(H)(micro-ECp)}2] (, E=Ga; , E=Al) and [{CpRu}3(micro-H)5(micro3-ECp)] (, E=Al; , E=Ga). All Ru complexes react upon coordination of the group 13 ligand without loss of H2 or reductive elimination of Cp*H and without insertion into the Ru-H bonds; some of the products, however, showing Ru-H-E bridging motifs. All compounds were characterized by NMR spectroscopy, elemental analysis and single crystal X-ray diffraction studies.
研究了氢化钌配合物[{Ru(COD)(H)(NH2NMe2)3}{BArF}]（BArF = B{C6H3(CF3)2}4）、[{CpRu}2(μ-H)4]和[{CpRu}3(μ-H)3(μ3-H)2]与GaCp和AlCp的反应。[{Ru(COD)(H)(NH2NMe2)3}{BArF}]与GaCp反应导致肼配体被GaCp取代并形成[{Ru(COD)(H)(GaCp*)3}{BArF}]（），而[{CpRu}2(μ-H)4]和[{CpRu}3(μ-H)3(μ3-H)2]与ECp*（E = Al、Ga）反应生成多氢簇[{CpRu(μ-H)(H)(μ-ECp)}2]（，E = Ga；，E = Al）和[{CpRu}3(μ-H)5(μ3-ECp)]（，E = Al；，E = Ga）。所有钌配合物在与第13族配体配位时发生反应，不会损失H2或还原消除Cp*H，也不会插入Ru-H键；然而，一些产物显示出Ru-H-E桥连 motif。所有化合物均通过核磁共振光谱、元素分析和单晶X射线衍射研究进行了表征。
