    使用可见光对肟进行光催化三重态敏化,为非经典贝克曼重排产物提供了一条途径
    摘要:
    肟是用于制备各种官能团的有价值的合成中间体。迄今为止,肟的立体选择性合成仍然是一个主要挑战,因为大多数当前的合成方法要么提供E和Z异构体的混合物,要么提供热力学上优选的E异构体。在此,我们报告了一种温和而通用的方法,通过可见光介导的能量转移 (EnT) 催化对肟进行光异构化,从而获得芳基肟的Z异构体。轻松访问 ( Z)-肟提供了实现区域选择性和化学选择性的机会,与那些广泛使用的使用肟起始材料的转化互补。我们展示了一种用于光催化肟异构化和随后的贝克曼重排的增强型一锅法方案,该方案可实现与烷基优先于芳基迁移的新型反应性,从而逆转传统贝克曼反应的区域选择性。还证明了烯基肟的化学发散性N - 或O - 环化,分别导致硝酮或环肟醚。

  • Iron-Catalyzed <i>Ortho</i> C–H Methylation of Aromatics Bearing a Simple Carbonyl Group with Methylaluminum and Tridentate Phosphine Ligand

    (Me2N-TP), that allows us to convert an ortho C-H bond to a C-CH3 bond in aromatics and heteroaromatics bearing simple carbonyl groups under mild oxidative conditions. The reaction is powerful enough to methylate all four ortho C-H bonds in benzophenone. The reaction tolerates a variety of functional groups, such as boronic ester, halide, sulfide, heterocycles, and enolizable ketones.
    近年来,芳烃的铁催化 CH 官能化引起了化学家的广泛关注,但由于需要在底物上精心设计导向基团,迄今为止阻碍了苯甲酸和酮等简单芳香羰基化合物的使用,大大减少了其合成公用事业。我们在这里描述了温和反应性甲基铝试剂和用于金属催化的新三齿膦配体 4-(双(2-(二苯基膦基)苯基)膦基)-N,N-二甲基苯胺 (Me2N-TP) 的组合,这使我们能够在温和的氧化条件下将带有简单羰基的芳烃和杂芳烃中的邻位 CH 键转化为 C-CH3 键。该反应足够强大,可以甲基化二苯甲酮中的所有四个邻位 CH 键。该反应耐受多种官能团,如硼酸酯、

    Acyliron complexes, easily prepared from disodium tetracarbonylferrate and alkyl halides, reacted with aryl iodides in the presence of a catalytic amount of Pd(PPh3)4 and a cocatalyst, ZnCl2, to give aromatic ketones in good yields. (R)-2-Methyl-1-phenyl-1-octanone was prepared starting from (S)-2-bromooctane in an excellent optical yield.
