    Nitration of Strongly Deactivated Aromatics with Superacidic Mixed Nitric-Triflatoboric Acid (HNO3/2CF3SO3H-B(O3SCF3)3)
    摘要:
    The nitration of various deactivated arenes (including methanesulfonyl-, nitro-, and polyhalobenzenes) was carried out in good yield with mixed nitric-triflatoboric superacid. For example pentafluorobenzene gave pentafluoronitrobenzene in 99% yield, nitrobenzene to m-dinitrobenzene in 92% selectivity with 85% overall yield, and methyl phenyl sulfone gave only the m-nitro isomer in 78% isolated yield. Thus the new nitrating system gives high regioselectivity and yields under generally mild reaction conditions. The reagent system is compatible with many functional groups of arenes.

  • Fe-Mediated Nitrogen Fixation with a Metallocene Mediator: Exploring p<i>K</i><sub>a</sub> Effects and Demonstrating Electrocatalysis

    especially where the competing hydrogen evolution reaction (HER) is thermodynamically and kinetically competent. In this study, we investigate how the selectivity of a tris(phosphine)borane iron(I) catalyst, P3BFe+, for catalyzing the nitrogen reduction reaction (N2RR, N2-to-NH3 conversion) versus HER changes as a function of acid p Ka. We find that there is a strong correlation between p Ka and N2RR efficiency
    N2、CO2 和 O2 等小分子还原多电子/质子催化中的底物选择性是催化剂设计的主要挑战,特别是在竞争性析氢反应 (HER) 具有热力学和动力学能力的情况下。在本研究中,我们研究了三(膦)硼烷铁(I)催化剂 P3BFe+ 催化氮还原反应(N2RR、N2-to-NH3 转化)与 HER 的选择性如何随酸 p Ka 的变化而变化。我们发现 p Ka 和 N2RR 效率之间存在很强的相关性。化学计量研究表明,所用的苯胺三氟甲磺酸盐仅在茂金属还原剂Cp*2Co存在的情况下与N2还原的早期中间体(例如Fe(NNH)或Fe(NNH2))的形成相容。这表明酸和还原剂的相互作用在 NH 键形成反应中发挥着关键作用。DFT 研究确定质子化茂金属物质是强 PCET 供体,并表明它应该能够形成对 N2RR 至关重要的早期 NH 键。此外,DFT 研究还表明,观察到的 p Ka 对 N2RR 效率的影响可归因于不同苯胺酸的
  • Carbomethoxylating reactivity of methyl phenyl carbonate toward aromatic amines in the presence of group 3 metal (Sc, La) triflate catalysts

    Methyl phenyl carbonate (MPC) has been investigated as a carbomethoxylating agent of aromatic amines in the presence of group 3 metal (Sc or La) triflate catalysts. Under mild conditions (363 K), both Sc(OTf)3 and La(OTf)3 (OTf = O3SCF3) can promote the carbamation of aniline and a few industrially relevant aromatic diamines, such as 4,4′-methylenedianiline (MDA) and 2,4-diaminotoluene (TDA), with
    已经研究了在第3组金属(Sc或La)三氟甲磺酸酯催化剂的存在下,碳酸甲基苯基苯酯(MPC)作为芳族胺的羰基甲氧基化剂。在温和条件下(363 K),Sc(OTf)3和La(OTf)3(OTf = O 3 SCF 3)均可促进苯胺和一些工业上有用的芳族二胺的氨化反应,例如4,4'-亚甲基二苯胺(MDA)和2,4-二氨基甲苯(TDA),以及MPC。氨基甲酸酯的收率和选择性受实验条件(温度,反应介质,金属中心的性质)的显着影响。Sc(OTf)3是比La(OTf)3更有效和选择性的氨基甲酸酯化催化剂。临时实验表明,在M(OTf)3(M = Sc,La)催化剂的存在下,MPC不仅比碳酸二甲酯(DMC)具有更高的反应活性,而且具有更高的选择性羰基甲氧基化剂。

    showed that the less common addition to an η3-benzyl complex is faster than the more common addition to an η3-allyl complex. The relative rates of reaction followed the trend naphthylmethyl > naphthylethyl > benzyl > 1,1-dimethylallyl > allyl. Computational studies suggest that there is a correlation between the amount of positive charge at the site of nucleophilic attack and the rate of C−N bond formation
    亲核试剂与以 η3 方式键合的金属键合烃基 π-配体的反应是各种碳-碳和碳-杂原子键形成反应的关键步骤。为了揭示控制亲核试剂与此类配体反应速率的因素,芳香胺和脂肪胺与一系列由双膦连接的 η3-烯丙基、η3-苄基和 η3-苯乙基钯配合物的反应速率测量(R)-BINAP形成烯丙基胺和苄胺。这些数据表明,对 η3-苄基络合物的不太常见的加成比对 η3-烯丙基络合物的更常见的加成更快。反应的相对速率遵循以下趋势:萘甲基>萘乙基>苄基>1,1-二甲基烯丙基>烯丙基。

    A series of [Cp*Rh] complexes (Cp* = η5-pentamethylcyclopentadienyl) bearing the κ2-[P,N]-8-(diphenylphosphino)quinoline (PQN) ligand have been prepared and characterized. Chemical or electrochemical reduction of the rhodium(III) form generates an isolable rhodium(I) complex; this rhodium(I) complex reacts with a range of organic acids to yield a rhodium(III) hydride bearing [Cp*] in the η5 mode and
