    离子液体对用于醛加氢的 SILP Fe(II) 钳形催化剂活性的影响
    摘要:
    使用 FeII 氢化物钳形配合物作为负载离子液相 (SILP) 反应模式中的催化剂,研究了不同醛催化氢化成相应的醇。两种不同的 [X4441][NTf2] 类型的离子液体,X=N 或 P,以介孔硅胶为载体,首先用相应改性 IL 的化学吸附单层包被,以去除酸性表面 OH-基团并防止IL浸出。对于各种芳香族和杂芳香族醛,获得了转换频率为 1000 h-1 数量级的定量转化,并且对于含有可还原 C=C 键的底物也观察到了高度选择性的醛还原。然而,具有更长脂肪链或环烷基取代基的醛在这里没有显示出转化,与之前使用咪唑基离子液体的研究形成对比。这些差异主要归因于底物/离子液体相互作用的差异。尽管 [N4441][NTf2] 和 [P4441][NTf2] 在单批反应中对不同底物给出了基本相同的结果,但在重复反应循环中长时间使用催化剂会导致 [P4441] 中催化剂活性的快速下降[NTf2],但在 [N4441][NTf2]

  • Chemoselective Hydrogenation of Aldehydes under Mild, Base-Free Conditions: Manganese Outperforms Rhenium
    作者:Mathias Glatz、Berthold Stöger、Daniel Himmelbauer、Luis F. Veiros、Karl Kirchner

    catalysts for the homogeneous chemoselective hydrogenation of aldehydes. Among these, [Mn(PNP-iPr)(CO)2(H)] was found to be one of the most efficient base metal catalysts for this process and represents a rare example which permits the selective hydrogenation of aldehydes in the presence of ketones and other reducible functionalities, such as C=C double bonds, esters, or nitriles. The reaction proceeds
    几种氢化物Mn(I)和Re(I)PNP钳形配合物用作醛的均相化学选择性氢化的催化剂。其中,[Mn(PNP-iPr)(CO)2(H)]被发现是该方法中最有效的贱金属催化剂之一,是一个罕见的例子,它允许在酮存在下对醛进行选择性加氢以及其他可还原的官能团,例如C = C双键,酯或腈。反应在室温下在无碱条件下进行,催化剂负载量为0.1至0.05 mol%,氢气压力为50 bar(TON达到2000)。提出了一种涉及外球氢化物转移和可逆PNP配体去质子化/质子化的机理。类似的等电子和同构Re(I)配合物的活性很差。
