  用铬催化的环状（烷基）（氨基）卡宾配体促进的硝基脱氧硼氢化反应：范围、机制和应用

  摘要：

  利用 N-杂环卡宾作为非无害配体促进转化的过渡金属催化尚未得到很好的研究。我们在这里报告了具有成本效益的铬催化的环状（烷基）（氨基）卡宾（CAAC）配体促进的硝基脱氧硼氢化反应。使用 1 mol % 的 CAAC-Cr 预催化剂，将 HBpin 添加到硝基支架上会导致脱氧，从而保留各种可还原的官能团和敏感基团对硼氢化的相容性，从而提供一种温和、化学选择性和易于形成的策略苯胺，以及杂芳基和脂肪胺衍生物，具有广泛的范围和特别高的转换数（高达 1.8 × 106）。基于理论计算的机械研究，表明CAAC配体在促进HBpin氢化物极性反转中起重要作用；它用作 H 穿梭以促进脱氧硼氢化。通过这种策略制备的几种市售药物突出了其在药物化学中的潜在应用。

  摘要：

  链之间含有α-CH的1,3-二酮的双-（4-硝基苯基hydr）氧化会导致环化并断裂，生成吡唑。该反应被认为涉及双-的共轭互变异构烯胺形式的脱氢，得到顺式-偶氮-hydr烯链中间体。当假定的偶氮-hydr氮烯中间体具有反式时-立体化学，不利于环化，如在环己-1,3-二酮双-（4-硝基苯基hydr）的氧化中，偶氮-烯烃是稳定的并且是主要产物。当1,3-双bis的共轭烯胺互变异构形式不存在时，与3,3-二甲基戊烷-2,4-二酮双-（4-硝基苯基hydr）一样，不形成吡唑，the链表现为分离的单hydr。

• Aromatic N-Arylations Catalyzed by Copper-Anchored Porous Zinc-Based Metal-Organic Framework under Heterogeneous Conditions
  作者：Tanmoy Maity、Debraj Saha、Subratanath Koner

  日期：2014.8

  A highly porous Zn‐based metal–organic framework (MOF) IRMOF‐3 was covalently decorated with pyridine‐2‐aldehyde. The free amine group of IRMOF‐3 upon condensation with pyridine‐2‐aldehyde affords a bidentate Schiff‐base moiety in the porous matrix. The Schiff base moieties are availed to anchor copper(II) ions to display the catalyst’s utility towards catalytic reactions. The catalyst was characterized

  高度多孔的锌基金属-有机骨架（MOF）IRMOF-3与吡啶-2-醛共价修饰。与吡啶-2-醛缩合后，IRMOF-3的游离胺基在多孔基质中提供双齿席夫碱部分。席夫碱部分可用于锚定铜（II）离子，以显示催化剂对催化反应的效用。通过紫外/可见光和红外光谱，粉末XRD光谱，SEM能量色散X射线光谱和氮吸附测量对催化剂进行了表征。在Cs 2 CO 3存在下，在温和条件下（90°C），该催化剂在DMSO介质中催化含氮杂环与芳基溴的N-芳基化反应具有出色的催化活性。。由于MOF的孔内存在活性位点，因此多孔催化剂表现出对底物的尺寸选择性。在多达五个连续的催化循环中，锚固的配合物似乎在催化反应过程中不会被浸出或分解，这显示出优于均相催化的实际优势。
