  • Reactions of 1-aryl-2,2-dihalogenoethanone oximes with tetrasulfur tetranitride (S4N4): a general method for the synthesis of 3-aryl-4-halogeno-1,2,5-thiadiazoles

    on the basis of 1H NMR spectroscopic evidence and an X-ray crystallographic analysis of 1-(3-chlorophenyl)-2,2-dichloroethanone oxime 7f. The 1-aryl-2,2-dihalogenoethanone oximes react with tetrasulfur tetranitride in refluxing 1,4-dioxane to give 3-aryl-4-chloro-1, 3-aryl-4-bromo-2, and 3-aryl-4-fluoro-1,2,5-thiadiazoles 3 in 69–98, 49–99, and 32–65% yields, respectively. A mechanism for the formation

  • Electrocatalytic synthesis of α,α-<i>gem</i>-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation

    However, when the aqueous solution contained NaOH, two α-mono-halide ketone molecules had a special dimer condensation. The reaction mechanisms were explored by conducting GC-MS, EPR, and CV with DFT calculations. These revealed that in situ generation of a halogen radical initiated electrocatalytic halogenation, while the dimer condensation involved a hydroxyl radical-mediated C1 fragment elimination.
    已经开发了一种新颖的、环境友好的电催化工艺,以在含有碱金属卤化物盐的水溶液中从 α-单卤化物酮制备 α,α-偕二卤化物(F、Cl 和 Br)酮。宝石_-二卤化物可以在相同的碳上具有相同或不同的卤素,这取决于所使用的反应物和无机卤化物盐。位于单卤代碳的α位的吸电子基团,如羰基,对反应至关重要。电合成在没有惰性气体保护的环境条件下进行,产率约为 80%。该方法避免了经典的卤仿消除反应。然而,当水溶液中含有NaOH时,两个α-单卤酮分子发生了特殊的二聚体缩合。通过使用 DFT 计算进行 GC-MS、EPR 和 CV 来探索反应机制。这些揭示了现场卤素自由基的产生引发了电催化卤化,而二聚体缩合涉及羟基自由基介导的 C1 片段消除。

  • Asymmetric Organocatalytic Monofluorovinylations
    作者:Christian Borch Jacobsen、Martin Nielsen、Dennis Worgull、Theo Zweifel、Esben Fisker、Karl Anker Jørgensen
    DOI:10.1021/ja110624k
    日期:2011.5.18
    The development of highly enantio- and c organocatalytic monofluorovinylations is presented. Based on the application of alpha-fluoro beta-keto-benzothiazolesulfones, the formal addition of a monofluorovinylic anion synthon to a range of acydic and cyclic enones, as well as imines, is shown. These procedures give selective access to both E- and Z-isomers of the monofluorovinylated products, which are isolated as the pure diastereoisomers in good to excellent yields with up to 99% ee. Furthermore, the application of this concept for the formation of highly enantioenriched bicylic compounds containing a monofluorovinyl moiety is also described. In addition, a mechanistic rationale for the observed E:Z-selectivities is presented.

    A nickel-catalyzed coupling reaction of α-bromo-α-fluoroketones with arylboronic acids was reported, which provides an efficient pathway to access 2-fluoro-1,2-diarylethanones in high yields. We also disclosed the synthesis of the monofluorination agents α-bromo-α-fluoroketones by using a trifluoroacetate release protocol. Mechanistic investigation indicated that a monofluoroalkyl radical is involved
