Treatment of [RuCl₂(PPh₃)₃] with N-(β-aminoethyl)-γ-aminopropylmethylbimethoxysilane (L1) in tetrahydrofuran at room temperature gave a mononuclear ruthenium(II) complex [Ru(PPh₃)₂Cl₂ (κ²-N,N-L1)] (1). Condensation of γ-aminopropyltriethoxysilane and potassium diphenylphosphine in the molar ratio of 1:1 in tetrahydrofuran afforded phosphine (PPh₂)(CH₂)₃Si(OEt)₃ (L2) with ethoxysilane groups. Reaction of [Ru(η⁶-p-cymene)Cl₂]₂ with L2 in refluxing tetrahydrofuran afforded a ruthenium(II) phosphine complex [Ru(η⁶-p-cymene)Cl₂(κ-P-L2)] (2). Complexes 1 and 2 were systematically characterized by microanalyses, FT-IR, and NMR spectroscopies. Their structures have been unambiguously established by single-crystal X-ray diffraction. Immobilization of 1 and 2 on SBA-15 and characterization of these hybrid heterogeneous catalysts were studied by transmission electron microscopy (TEM), FT-IR, and low-pressure N₂ adsorption/desorption measurements. Transfer hydrogenation of acetophenone was also briefly investigated with the heterogeneous catalysts.

在室温下在四氢呋喃中用N-（β-氨基乙基）-γ-氨基丙基甲基联甲氧基硅烷（L1）处理[RuCl ₂（PPh ₃）₃ ]得到单核钌（II）络合物[Ru（PPh ₃）₂ Cl ₂（κ）² - N，N - L1）]（1）。γ-氨基丙基三乙氧基硅烷和二苯基膦钾盐在四氢呋喃中以1：1的比例缩合得到膦（PPh ₂）（CH ₂）具有乙氧基硅烷基团的₃ Si（OEt）₃（L2）。的反应的[Ru（η ⁶ - p -cymene）氯₂ ] ₂与L2在回流的四氢呋喃中，得到钌（II）膦络合物的[Ru（η ⁶ - p -cymene）氯₂（κ - P - L2）]（2）。配合物1和2通过微量分析，傅立叶变换红外光谱（FT-IR）和核磁共振光谱（NMR）进行系统表征。它们的结构已通过单晶X射线衍射明确建立。通过透射电子显微镜（TEM），FT-IR和低压N ₂吸附/脱附测量研究了1和2在SBA-15上的固定以及这些杂化多相催化剂的表征。还用非均相催化剂对苯乙酮的转移氢化进行了简要研究。
