    名称:
    Efficient Cobalt-Catalyzed Oxidative Conversion of Lignin Models to Benzoquinones
    摘要:
    Phenolic lignin model monomers and dimers representing the primary substructural units of lignin were successfully oxidized to benzoquinones in high yield with molecular oxygen using new Co-Schiff base catalysts bearing a bulky heterocyclic nitrogen base as a substituent. This is the first example of a catalytic system able to convert both S and G lignin model phenols in high yield, a process necessary for effective use of lignin as a chemical feedstock.

  • Macrocyclic Mn(III) salen complexes as recyclable catalyst for oxidative kinetic resolution of secondary alcohols
    作者:Prasanta Kumar Bera、Nabin Ch. Maity、Sayed H.R. Abdi、Noor-ul H. Khan、Rukhsana I. Kureshy、Hari C. Bajaj
    DOI:10.1016/j.apcata.2013.07.055
    日期:2013.10
    macrocyclic chiral Mn(III) salen complexes (C1–C4) were synthesized and were used as catalysts for oxidative kinetic resolution (OKR) of secondary alcohols with diacetoxyiodobenzene (PhI(OAc)2) and N-bromosuccinimide (NBS), in biphasic dichloromethane: water solvent mixture. Good to excellent enantioselectivities were achieved with catalyst C2 for several secondary alcohols having different steric environment
    合成了新的大环手性锰(III)赛伦络合物(C1 - C4),并用作双相双乙酰氧基碘苯(PhI(OAc)2)和N-溴代琥珀酰亚胺(NBS)的仲醇氧化动力学拆分(OKR)的催化剂二氯甲烷:水与溶剂的混合物。用催化剂C2对几种具有不同空间环境的仲醇实现了良好至优异的对映选择性。通常,在催化剂C2中,NBS作为助氧化剂比OKR中的PhI(OAc)2具有更好的对映选择性。催化剂C2通过添加己烷可以很容易地从反应混合物中回收三氯甲烷,并与NBS和PhI(OAc)2作为助氧化剂一起再循环七次,而不会损失其性能。基于实验结果,提出了外消旋1-苯基乙醇的OKR机理,其中(R,R)-Mn-salen优选与(S)-1-苯基乙醇结合,在(R)- (R)-1-苯基乙醇过量。反应结束。

    for exceptional catalytic turnover numbers (up to 15 400), which were increased by around 1.5–3 orders of magnitude compared to the most active catalysts previously reported. In our concept an aprotic ammonium halide moiety cooperates with an oxophilic Lewis acid within the same catalyst molecule. Control experiments reveal that both catalytic centers are essential for the observed activity. Kinetic
    对映纯仲醇是基本的高价值合成基石。进入这类化合物最吸引人的方法之一是催化硼氢化。我们描述了这种反应类型的新概念,该概念可实现出色的催化转换数(最多15400),与先前报道的最具活性的催化剂相比,催化转换数增加了约1.5–3个数量级。在我们的概念中,质子惰性的卤化铵部分与同一个催化剂分子中的亲氧路易斯酸协同作用。对照实验表明,两个催化中心对于观察到的活性都是必不可少的。动力学,光谱学和计算研究表明,氢化物的转移受到速率的限制,并且通过协同机制进行,其中硼中的氢化物被碘化物连续置换,N 2反应。该催化剂可在几个步骤中以高收率获得,发现在催化过程中稳定,易于回收并且可以重复使用10次,仍然有效工作。
  • Diastereodivergent Asymmetric 1,4-Addition of Oxindoles to Nitroolefins by Using Polyfunctional Nickel-Hydrogen-Bond-Azolium Catalysts
    作者:Melanie Mechler、René Peters
    DOI:10.1002/anie.201502930
    日期:2015.8.24
    groups, and an axially chiral bisimidazolium entity participate in the stereocontrol of the direct 1,4‐addition of oxindoles to nitroolefins. Both epimers of the 1,4‐adduct are accessible in excess on demand by changes to the ligand constitution and configuration. As the products have been reported to be valuable precursors to indole alkaloids, this method should allow access to their epimeric derivatives
    非对映异构性是催化不对称合成的挑战。对于许多反应类型,固有地优选一种非对映异构体的生成,而其他非对映异构体不能高效地直接获得并且需要circuit回合成方法。通过催化剂覆盖固有的偏好,需要控制两个反应伙伴的空间位置。我们报告了一种新型的多官能催化剂类型,其中Ni II-双(苯氧基亚胺)单元,游离羟基和轴向手性双咪唑鎓实体参与将吲哚直接1,4-加成到硝基烯烃的立体控制。1,4-加合物的两个差向异构体可通过改变配体的组成和构型按需获得。由于据报道该产品是吲哚生物碱的有价值的前体,因此该方法应允许获得其差向异构衍生物。

    Provided is a method of preparing poly(alkylene carbonate) using a molecular weight regulator in a process of preparing a copolymer of carbon dioxide/epoxide using a novel complex synthesized from salen-type ligand including a quaternary ammonium salt as a catalyst. According to the present invention, even though the molecular weight regulator is used, an activity of the catalyst may be stably maintained, whereby the low molecular weight of poly(alkylene carbonate) having a desirable level may be effectively provided. In addition, it is expected that since the novel complex as the catalyst of the present invention has a simple structure as compared to the existing copolymerization catalyst, due to the economical preparation cost thereof, the novel complex may be effectively applied to a large-scale commercial process.

    Lewis acid catalysis and nucleophilic carbene catalysis are complementary fundamental concepts to accelerate and control chemical reactions of aldehyde substrates. Their efficient merger has recently been achieved using two separate catalyst species. The present report describes our efforts to develop a cooperative catalyst system which incorporates both features Lewis acid and nucleophilic NHC –
    路易斯酸催化和亲核卡宾催化是互补的基本概念,用于加速和控制醛底物的化学反应。最近,使用两种独立的催化剂种类实现了有效的合并。本报告描述了我们在同一个催化剂实体中开发兼具两种特性(路易斯酸和亲核NHC)的协同催化剂体系的努力。为了在非常温和的条件下生成游离卡宾基团,形成了Ag-NHC络合物,并用PPh 3处理后释放出亲核卡宾。结果是形成烯醇-δ-内酯作为新的烯二聚产物。银对于反应模式是必不可少的,因此表明它在催化事件中起着双重作用。
