  • On the behaviour of Ru(I) and Ru(II) carbonyl acetates in the presence of H2 and/or acetic acid and their role in the catalytic hydrogenation of acetic acid

    and/or acetic acid was investigated by IR and NMR spectroscopy to clarify their role in the catalytic hydrogenation of acetic acid. Evidences were collected to suggest hydride ruthenium complexes as the catalytically active species. Equilibria among ruthenium hydrides and carboxylato complexes take place in the presence of hydrogen and acetic acid, that is in the conditions of the catalytic reaction. Nevertheless

    selectivity of these catalytic systems in the hydrogenation of quinoline: in all tests the three catalysts lead to 1,2,3,4-tetrahydroquinoline as the major product, furthermore this compound is the only formed in the presence of RuH2(CO)2(PPh3)2. The selectivity is affected by the presence of an acid (CH3COOH) or a base (NnBu3) in the reaction media. The complex RuH2(PPh3)4 is catalytically active, even if
    摘要分析了二配合物RuH2(CO)2(PnBu3)2,RuH2(CO)2(PPh3)2和RuH2(PPh3)4在含氮杂环加氢中的催化活性。反应参数(例如温度,氢气压力,催化剂浓度)对反应速率和区域选择性的影响。RuH2(PPh3)4表现出更好的催化活性,在100°C和25 bar氢气压力下24小时后,喹啉的转化率为86.7%,而RuH2(CO)2(PPh3)2和RuH2(CO)2(PnBu3) )2在相同条件下的转化率分别为37.1%和35.6%。这些结果由喹啉的氢化反应速率证实,因为在RuH2(PPh3)4存在下的Kc(1.46×10-5 s-1)高于其他(6.37×10-6 s-1) RuH2(CO)2(PPh3)2和6。对于RuH2(CO)2(PnBu3)2)为36×10-6 s-1。值得注意的是这些催化剂体系在喹啉加氢中的选择性:在所有测试中,三种催化剂均以1,2,3,4-四

    homodiphosphine precursors Ru(CO)2(OAc)2(PnBu3)2 and Ru(CO)2(OAc)2(PPh3)2. The catalytic activity of the heterodiphosphine complexes depends on the basicity of the triarylphosphine trans to PnBu3 as this factor controls, inter alia, the rate of formation of hydride(acetate), Ru(CO)2(H)(OAc)(PnBu3)[P(p-XC6H4)3], or dihydride, Ru(CO)2(H)2(PnBu3)[(p-XC6H4)3], complexes, by hydrogenation of the bis(OAc) precursors

    The catalytic activity of mononuclear and polynuclear ruthenium complexes in the benzo[b]thiophene (BT) hydrodesulfurization (HDS) has been tested in the temperature range between 150 and 170°C under 100 bar of hydrogen. The ruthenium complexes tested are shown to be catalytically active in the hydrogenation of BT to 2,3-dihydrobenzo[b]thiophene (DHBT) and 2-ethylthiophenol. The best performance was
    在150至170°C的温度范围内,在100 bar氢气下,已测试了单核和多核配合物在苯并[b]噻吩(BT)加氢脱(HDS)中的催化活性。所测试的络合物显示出在BT氢化为2,3-二氢苯并[b]噻吩(DHBT)和2-乙基苯酚中的催化活性。H 4 Ru 4(CO)8(PPh 3)4提供了最佳性能在170°C下工作时:在这些条件下,BT被氢化成DHBT,96小时后转化率为38.2%,384小时后转化为81.2%。还形成了乙苯(转化率为4.9%),证实可以得到底物的完整HDS(即使少量)。添加强碱(t BuOK)作为助催化剂会改变反应的化学选择性。单核复合物的活性低于聚簇的。实际上,在相同条件下,在Ru(CO)3(PPh 3)2存在下,BT最多可转化为DHBT的19.5%。这些数据表明该反应是通过催化中间体中几个属原子的协同作用而促进的。

    bis(acetate) complex Ru(CO)2(OAc)2(PnBu3)(PPh3) (OAc = acetate) containing two different trans phosphine ligands, has been employed as pre-catalyst for the chemoselective hydrogenation of α,β-unsaturated ketones to allylic alcohols. Analogous catalytic reactions with the homodiphosphine pre-catalysts Ru(CO)2(OAc)2(PnBu3)2 and Ru(CO)2(OAc)2(PPh3)2 gave lower conversions and selectivities. Batch catalytic reactions
