  high catalytic activity and stability in N- and C-alkylation reactions. A diverse range of N- and C-alkylation products were obtained in moderate to high yield under green and mild conditions in air. Also the N- and C-alkylation products can be obtained with different selectivity and yield by exposure reactions with EMF. Results of alkylation reactions showed that the presence of Fe(II) and Fe(III)

  过渡金属化合物已作为有机反应的合适催化剂出现。磁性化合物如柔软的路易斯酸可用作有机反应的催化剂。在该报告中，在没有任何保护剂的外部磁场（EMF）下，从Fe 2+和Fe 3+盐获得了Fe 3 O 4纳米结构。X射线光电子能谱，扫描电子显微镜和能量色散X射线能谱工具用于表征这些磁性化合物。二维（二维，它在二维中显示纳米尺寸，纳米棒结构）Fe 3 O 4该化合物在N和C烷基化反应中显示出高催化活性和稳定性。在绿色和温和的条件下，在空气中以中等至高收率获得了各种N-和C-烷基化产物。通过与EMF的暴露反应，也可以以不同的选择性和产率获得N-和C-烷基化产物。烷基化反应的结果表明，磁性催化剂表面（磁性化合物的相结构）上存在Fe（II）和Fe（III）物种是非常廉价的活性位点所必需的。而且，磁性催化剂的形态对其催化性能有影响。反应后，使用外部磁体可以轻松实现催化剂/产物的分离，并且可以回收超过95％的催化剂。

  日期：1987.1

  β-Nitrostyrenes are diprotonated on the nitro group to yield N,N-dihydroxyiminium-benzyl dications in trifluoromethanesulfonic acid. These dications comprise a new class of reagents that can react with benzene. The reaction is dependent on the substituent (H or alkyl group) at the β-position of nitrostyrene: β-nitrostyrene yields diphenylacetophenoneoxime, and β-methyl-β-nitrostyrene yields acetophenoneoxime

  β-硝基苯乙烯在硝基上被双质子化，从而在三氟甲磺酸中生成N，N-二羟基亚甲基-苄基阳离子。这些指示剂包括可以与苯反应的新型试剂。该反应取决于在硝基苯乙烯的β-位上的取代基（H或烷基）：β-硝基苯乙烯产生二苯基乙酰苯肟，而β-甲基-β-硝基苯乙烯产生乙酰苯肟和三苯基甲烷。建议在两个反应中都涉及一种基本共同的机制。这些反应是硝基烯烃的酸催化反应的新实例。
• Copper-mediated arylation with arylboronic acids: Facile and modular synthesis of triarylmethanes
  作者：H Surya Prakash Rao、A Veera Bhadra Rao

  DOI：10.3762/bjoc.12.49

  日期：——

  A facile and modular synthesis of triarylmethanes was achieved in good yield via a two-step sequence in which the final step is the copper(II)-catalyzed arylation of diarylmethanols with arylboronic acids. By using this protocol a variety of symmetrical and unsymmetrical triarylmethanes were synthesized. As an application of the newly developed methodology, we demonstrate a high-yielding synthesis of the triarylmethane intermediate towards an anti-breast-cancer drug candidate.

  A new solid acid Nafion-H, a perfluorinated sulfonic acid resin, catalyzed microwave-assisted synthesis of triarylmethanes is described. Various benzaldehydes react readily with arenes to provide the corresponding triarylmethanes in good to excellent yields. The reactions were carried out under solvent free conditions under microwave irradiation in a pressure vessel. The solvent free microwave irradiation
