  • Pyrolysis of (2-Phenylethyl)phenylsulfonium Ylides.
    作者:Toshiaki Yoshimura、Atsushi Motoyama、Akiko Morishige、Eiichi Tsukurimichi、Choichiro Shimasaki、Kiyoshi Hasegawa

    In order to obtain information concerning the reaction mechanism of the pyrolysis of sulfonium ylides bearing a substituted phenyl group on the 2-position in the S-ethyl group of ethylphenylsulfonium ylide, (2-phenylethyl)phenylsulfonium bis(methoxycarbonyl)methylide (1) and dicyanomethylide (2) were subjected to pyrolysis in benzene. The reaction rates of 1 and 2 at 140 °C were 6.0- and 3.2-times faster than those of ethylphenylsulfonium bis(methoxycarbonyl)methylide and dicyanomethylide, respectively. The activation parameters for 1 were ΔH‡ = 125 kJ mol−1 and ΔS‡ = −3.8 J K−1 mol−1, while those for 2 were ΔH‡ = 124 kJ mol−1 and ΔS‡ = −2.5 J K−1 mol−1. Substituent effects on the β-phenyl groups in 1 and 2 afforded positive Hammett ρ-values: ρ = 0.49 (γ = 0.997) and ρ = 0.26 (γ = 0.993), respectively.From the obtained results, it was suggested that the pyrolysis proceeds through essentially a concerted intramolecular cis-elimination inclined toward a slightly carbanion-like type from an E1-like type by introducing a phenyl substituent at the 2-position of the ethyl group in the ethylphenylsulfonium ylide.
    为了获取有关乙基苯基亚磺酸乙酯中乙基的2-位上带有取代苯基的磺酸亚磺酸分解反应机理的信息,将(2-苯乙基)苯基亚磺酸双(甲氧基羰基)甲亚基(1)和双氰基甲亚基(2)在苯中进行分解。在140°C时,1和2的反应速率分别比乙基苯基亚磺酸双(甲氧基羰基)甲亚基和双氰基甲亚基快6.0倍和3.2倍。1的活化参数为ΔH‡ = 125 kJ mol−1,ΔS‡ = -3.8 J K−1 mol−1,而2的活化参数为ΔH‡ = 124 kJ mol−1,ΔS‡ = -2.5 J K−1 mol−1。1和2中β-苯基的取代效应提供了正的Hammett ρ值:ρ = 0.49(γ = 0.997)和ρ = 0.26(γ = 0.993)。从得到的结果可以看出,通过在乙基苯基亚磺酸乙的乙基的2-位引入苯基取代基,基本上是通过倾向于稍微类似于碳负离子的顺式消除过程,从而类似于E1型反应。

    日期:2021.7.2
    alkyl bromides with arenesulfonyl cyanides catalyzed by Ni(acac)2 under reductive conditions to form unsymmetrical sulfides is developed. This approach for sulfide synthesis is practical, relies on available, unfunctionalized materials such as alkyl (pseudo)halides, and is scalable. This catalytic strategy provides a complementary method for the preparation of unsymmetrical alkyl–aryl sulfides under
    开发了未活化的烷基溴与芳烃磺酰氰在还原条件下由 Ni(acac) 2催化形成不对称硫化物的交叉亲电偶联。这种硫化物合成方法是实用的,依赖于可用的非官能化材料,例如烷基(伪)卤化物,并且具有可扩展性。这种催化策略为在温和条件下制备具有良好官能团耐受性的不对称烷基-芳基硫化物提供了一种补充方法。

    Herein, we described a new method for the preparation of thioethers through hydrothiolation of alkenes and alkynes, using sulfamic acid as a reusable catalyst. Generally, this new methodology afforded the desired products in very good yields, under metal and solvent-free conditions. Furthermore, the catalyst was easily recovered and reused for further catalytic reactions without loss of activity.
    在这里,我们描述了一种新的方法,该方法通过使用氨基磺酸作为可重复使用的催化剂,通过烯烃和炔烃的氢硫醇化来制备硫醚。通常,这种新方法可以在无金属和无溶剂的条件下以非常高的收率提供所需的产品。此外,该催化剂易于回收并重新用于进一步的催化反应而不会损失活性。
  • Radical-Mediated Strategies for the Functionalization of Alkenes with Diazo Compounds

    reported. Here we report a novel reaction of diazo compounds utilizing a radical-mediated addition strategy to achieve difunctionalization of diverse alkenes. Diazo compounds are transformed to carbon radicals with a photocatalyst or an iron catalyst through PCET processes. The carbon radical selectively adds to diverse alkenes delivering new carbon radical species, then forms products through hydroalkylation
    重氮化合物与烯烃最常见的反应之一是通过金属卡宾或游离卡宾中间体发生的环丙烷化反应。烯烃与重氮化合物的替代官能化是有限的,并且还没有通过碳碳双键添加 Z-CHR2 元素(Z = H 或杂原子,CHR2 源自 N2 = CR2)的方法报道。在这里,我们报告了一种利用自由基介导的加成策略实现多种烯烃双官能化的重氮化合物的新反应。重氮化合物在光催化剂或铁催化剂的作用下通过 PCET 过程转化为碳自由基。碳自由基选择性地添加到不同的烯烃中,提供新的碳自由基物种,然后通过硫醇辅助的氢原子转移 (HAT) 通过加氢烷基化形成产物,或通过铁催化循环形成叠氮烷基化产物。这两个过程是高度互补的,在温和的反应条件下进行,并表现出高度的官能团耐受性。此外,这两种转化都在克级规模上成功进行,并且可以使用市售试剂轻松制备各种 γ-氨基酯、γ-氨基醇和复杂的螺内酰胺。机理研究揭示了将这两个过程联系起来的合理途径,并解释
  • Brønsted Acid-Assisted Zinc-Catalyzed Markovnikov-Type Hydrothiolation of Alkenes Using Thiols
    作者:Nobukazu Taniguchi
    DOI:10.1021/acs.joc.0c00487
    日期:2020.5.15
    hydrothiolation of alkenes with thiols was achieved in the presence of 4-toluenesulfonic acid. Through this procedure, Markovnikov-type sulfides were synthesized in excellent yields, and the formation of anti-Markovnikov-type sulfides was suppressed. Furthermore, the combination of numerous aryl alkenes with arenethiols or alkyl thiols was achieved using the procedure.
