  樟脑磺酸盐基离子液体对β-氨基羰基化合物动力学，热力学和立体选择性的反离子作用机理研究

  摘要：

  催化作用在有机化学的各种应用中很重要，其对立体选择化合物的输出产物控制非常苛刻。通过催化作用建立立体选择性化合物的实验事实，并使用理论证据对其进行验证，是理解旋光化合物各种机理的关键。已经合成了具有各种咪唑鎓阳离子和樟脑磺酸根阴离子作为对环境有益的液态盐的一系列新型离子液体（IL），并将其用于催化β-氨基羰基化合物。使用IL作为均相催化剂形成产物，具有优异的产物收率和非对映选择性。根据反应动力学和产物收率，研究了抗衡离子，IL的哈米特酸度和粘度以及溶剂和温度的影响。密度泛函理论（DFT）用于研究反应机理的热力学研究。DFT计算预测，催化机理涉及IL的两个抗衡离子。此外，有证据表明，合成途径需要较低的活化能，而反途径产生热力学稳定的产物。这项研究探索了使用IL作为潜在的均相催化剂生产立体选择性物质的新途径。

• Pronounced Catalytic Effect of a Micellar Solution of Sodium Dodecylsulfate (SDS) Upon a Three-Component Reaction of Aldehydes, Amines, and Ketones Under Neutral Conditions

  日期：2009.3

  A micellar solution of anionic, cationic or neutral surfactants can be used as an excellent medium for three-component Mannich reactions of aldehydes, amines, and ketones at room temperature. Sodium dodecylsulfate turned out to efficiently catalyze the reaction in neutral pure water (pH ≈ 7), and the corresponding desired β-amino ketones precipitate while the reactions proceedes. This method provides

• H3PW12O40 supported on silica-encapsulated γ-Fe2O3 nanoparticles: a novel magnetically-recoverable catalyst for three-component Mannich-type reactions in water

  A new type of magnetically-recoverable catalyst was synthesized by the immobilization of H3PW12O40 on the surface of silica-encapsulated γ-Fe2O3 nanoparticles. This catalyst was characterized by transmission electron microscopy (TEM), a laser particle size analyzer, infrared spectroscopy (IR) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The results show that the particles are mostly spherical in shape and have an average size of approximately 94 nm. The characterization data derived from IR spectroscopy reveal that H3PW12O40 on the support exists in the Keggin structure. The acidity of the catalyst was measured by a potentiometric titration with n-butylamine. To our surprise, this very strong solid acid catalyst showed an excellent distribution of acid sites, suggesting that the catalyst possesses a higher number of surface active sites compared to its homogeneous analogues. The activity of the catalyst was probed through one-pot three-component Mannich-type reactions of aldehydes, amines and ketones in water at room temperature. The excellent conversions show that the catalyst has strong and sufficient acidic sites, which are responsible for its catalytic performance. After the reaction, the catalyst/product separation could be easily achieved with an external magnetic field, and more than 95% of the catalyst could usually be recovered. The catalyst was reused at least five times without any loss of its high catalytic activity.

  通过将H3PW12O40固定在二氧化硅包覆的γ-Fe2O3纳米颗粒表面，合成了一种新型磁性可回收催化剂。该催化剂通过透射电子显微镜（TEM）、激光粒度分析仪、红外光谱（IR）和电感耦合等离子体原子发射光谱（ICP-AES）进行了表征。结果显示，颗粒主要呈球形，平均尺寸约为94纳米。红外光谱表征数据揭示，负载上的H3PW12O40以Keggin结构存在。催化剂的酸度通过用正丁胺进行的电位滴定法测量。令人惊讶的是，这种非常强的固体酸催化剂显示出优异的酸位点分布，表明催化剂相对于均相类似物具有更高的表面活性位点数量。催化剂的活性通过在水中的室温下进行的一锅法三组分Mannich型反应，即醛、胺和酮的反应来评估。优异的转化率表明，催化剂具有强烈且充分的酸性位点，这是其催化性能的原因。反应后，通过外部磁场可以轻松实现催化剂/产物分离，通常可以回收超过95%的催化剂。该催化剂至少可以重复使用五次，而不会损失其高催化活性。

  A series of organoantimony(III) halide complexes with a tetrahydrodibenzo[c,f][1,5]azastibocine framework were synthesized and employed as water tolerant Lewis acid catalysts. The results of a systematic structure–activity relationship study demonstrated that the strength of N→Sb donor–acceptor interaction could be synergistically modulated by tuning the properties of the nitrogen substituents and

  合成了一系列具有四氢二苯并[ c，f ] [1,5]氮杂二bocine骨架的有机锑（III）卤化物配合物，并用作耐水路易斯酸催化剂。系统的结构-活性关系研究的结果表明，N→Sb供体-受体相互作用的强度可通过调节邻近中心锑原子的氮取代基和卤素原子的性质来协同调节，从而导致明显的催化作用。表现有机反应，如曼尼希，交叉缩合，环化-芳构化和环氧化物氨解反应。氟化有机锑（Ⅲ））由于使用Sb–F部分作为氢键受体，因此发现其衍生物比氯化，溴化和碘化的类似物更具活性。相比之下，发现化合物6-环己基-12-氟-5,6,7,12-四氢二苯并[ c，f ] [1,5]氮杂stibocine（1d）具有最高的催化活性，并且在规模扩大综合。
