  • Carbocations as Lewis Acid Catalysts in Diels-Alder and Michael Addition Reactions
    作者:Juho Bah、Johan Franzén
    DOI:10.1002/chem.201304160
    日期:2014.1.20
    the carbocation as a highly powerful Lewis acid catalyst for organic reactions. The stable and easily available triphenylmethyl (trityl) cation was found to be a highly efficient catalyst for the Diels–Alder reaction for a range of substrates. Catalyst loadings as low as 500 ppm, excellent yields, and good endo/exo selectivities were achieved. Furthermore, by changing the electronic properties of the
    通常,路易斯酸催化剂是基于金属的化合物,由于它们对低位的空轨道具有反应性。然而,碳阳离子是一种潜在的路易斯酸,已被忽略不计,它是一种催化剂。我们已经证明了碳正离子化作为有机反应的强力路易斯酸催化剂的潜力。稳定且容易获得的三苯甲基(三苯甲基)阳离子被发现是用于多种底物的Diels-Alder反应的高效催化剂。催化剂负载量低至500 ppm,优异的收率和良好的内/外达到了选择性。此外,通过改变三苯乙铵离子上取代基的电子性质,可以调节催化剂的路易斯酸度以控制反应的结果。该碳阳离子作为路易斯酸催化剂的能力也进一步扩展到迈克尔反应。
  • Recyclable organotungsten Lewis acid and microwave assisted Diels–Alder reactions in water and in ionic liquids
    作者:I-Hon Chen、Jun-Nan Young、Shuchun Joyce Yu
    DOI:10.1016/j.tet.2004.09.078
    日期:2004.12
    water-soluble, organotungsten Lewis acid, [OP(2-py)3W(CO)(NO)2](BF4)2 (1), was synthesized and characterized. A series of 1-catalyzed Diels–Alder reactions were investigated under conventional heating or microwave heating conditions. The cycloaddition reactions were efficiently conducted in either water or in an ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate. The ionic liquid acts as a powerful
    合成并表征了水溶性有机钨路易斯酸[OP(2-py)3 W(CO)(NO)2 ](BF 4)2(1)。在常规加热或微波加热条件下,研究了一系列1催化的Diels–Alder反应。环加成反应在水或离子液体六氟磷酸1-丁基-3-甲基咪唑鎓中有效进行。离子液体不仅用作提高速率和选择性的有力介质,而且还有助于促进催化剂的循环利用。与热加热相比,观察到通过微波闪蒸加热的剧烈速率加速。

    作者:Thiemo Arndt、Philip K. Wagner、Jonas J. Koenig、Martin Breugst
    DOI:10.1002/cctc.202100342
    日期:2021.6.18
    The Diels-Alder cycloaddition is the most popular pericyclic reaction with numerous applications in synthesis and catalysis. We now demonstrate that we can perform this reaction under mild and metal-free conditions relying on molecular iodine as the catalyst. Cycloadditions with cyclohexadiene, cyclopentadiene, or isoprene with various dienophiles can be performed typically within minutes in moderate
    Diels-Alder 环加成反应是最流行的周环反应,在合成和催化中有许多应用。我们现在证明我们可以依靠分子碘作为催化剂在温和且无金属的条件下进行该反应。用环己二烯,环戊二烯,或异戊二烯与各种亲双烯体环加成可在温和地通常执行分钟内良好的产率和高的内选择性。包括动力学和 DFT 研究在内的机械研究清楚地表明了卤素键激活并排除了其他激活模式。此外,碘的性能与典型的金属路易斯酸如 AlCl 3、SnCl 4或 TiCl 4 一样好。

    DOI:10.1016/s0040-4039(00)80045-3
    日期:1988.1
    The development of a new method for effecting [4+2] cycloadditions on the surface of chromatographic adsorbents in the absence of solvents that leads to a moderation of the reaction conditions and an increase in selectivity is described.
    描述了在不存在溶剂的情况下在色谱吸附剂表面进行[4 + 2]环加成反应的新方法的开发,该方法导致反应条件的缓和和选择性的提高。
  • Taming the Silylium Ion for Low-Temperature Diels-Alder Reactions
    作者:Hendrik F. T. Klare、Klaus Bergander、Martin Oestreich
    DOI:10.1002/anie.200904520
    日期:2009.11.16
    trivalent silicon cation stabilized by an electron‐rich transition metal as the “hot” Lewis acidic site catalyzes challenging Diels–Alder reactions at low temperatures with excellent reaction rates and selectivities (see scheme). In addition to the chemical stability of the silylium ion catalyst (in CH2Cl2), the potential of these reactive compounds is also discussed.
    有些人喜欢它:一种新型的基于硅的路易斯酸,具有三价硅阳离子,该阳离子被富电子的过渡金属稳定,作为“热”路易斯酸性位点,可在低温下催化具有挑战性的Diels-Alder反应,并具有出色的反应速率和选择性(请参见方案)。除了硅离子催化剂的化学稳定性(在CH 2 Cl 2中)之外,还讨论了这些反应性化合物的潜力。
