  • Metal-Free Benzylic C−H Amination via Electrochemically Generated Benzylaminosulfonium Ions
    作者:Ryutaro Hayashi、Akihiro Shimizu、Yetao Song、Yosuke Ashikari、Toshiki Nokami、Jun-ichi Yoshida

    toluene derivatives in the presence of N‐tosyldiphenylsulfilimine gave the corresponding benzylaminosulfonium ions, which were treated with tetrabutylammonium iodide under non‐electrolytic conditions to give N‐tosylbenzylamines. The transformation serves as a metal‐ and chemical‐oxidantfree method for benzylic C−H amination. Because of high oxidation potential of N‐tosyldiphenylsulfilimine the present
    在N-甲苯磺酰基二苯硫亚胺的存在下对甲苯衍生物进行电化学氧化,得到相应的苄基氨基离子,将其在非电解条件下用碘化四丁基铵处理,得到N-甲苯磺酰基苄基胺。该转变可作为无金属和化学氧化剂的苄基CH氨基化方法。由于N-甲苯磺酰基二苯硫亚胺具有很高的氧化潜能,因此本方法可用于从功能化的甲苯衍生物合成各种苄胺。
  • Reactions of Charged Substrates. 8. The Nucleophilic Substitution Reactions of (4-Methoxybenzyl)dimethylsulfonium Chloride

    product ratios suggests that at low [Nu] reaction occurs simultaneously through concerted Hughes-Ingold S(N)2 and preassociation-concerted mechanisms. At high [Nu], displacement occurs only through the preassociation-concerted mechanism. Comparison of these results with data for gas-phase dissociation of benzyl dimethylsulfoniums and with solution results for benzyl pyridiniums suggests that the intrinsic
    仅对于具有中等硬度的亲核试剂,发生在标题化合物(1)上的置换反应。反应的亲核试剂显示出多种机制。1通过混合的S(N)1 / S(N)2机理与中性亲核吡啶-d(5)反应;加入盐以控制离子强度会影响单分子过程的速率,但对双分子速率常数没有影响。N(3)(-)和SO(3)(2)(-)取代的机理取决于是否存在外源盐。在恒定的离子强度下,机理是在[Nu]的大部分范围内混合S(N)1 / S(N)2。仅存在亲核试剂时,k(obsd)对[Nu]的图显示出严重的断裂,这不是盐效应的结果。速率常数和产物比率的分析表明,在低[Nu]反应下,会通过协调的休斯-英戈尔德S(N)2和预先缔合的机制同时发生。在高[Nu]时,位移仅通过预先关联确认的机制发生。将这些结果与苄基二甲基ulf的气相解离数据和苄基吡啶鎓的溶液结果进行比较表明,中间体的内在稳定性不一定决定其机理。

  • Reactions of Charged Substrates. 4. The Gas-Phase Dissociation of (4-Substituted benzyl)dimethylsulfoniums and -pyridiniums
    作者:Neil Buckley、David Maltby、Alma L. Burlingame、Norman J. Oppenheimer
    DOI:10.1021/jo951257w
    日期:1996.1.1
    The relative rates for the gas-phase dissociation RX(+) --> R(+) + X degrees of five (4-Y-substituted benzyl)-dimethysulfoniums (Y = MeO, Me, H, Cl, and NO2) and 24 (4-Y-substituted benzyl)-3'-Z-pyridiniums (complete series for Z = CN, Cl, CONH2, and H, and 4-methoxy- and 4-nitrobenzyls for Z = F and CH3CO) were measured using liquid secondary ion mass spectrometry. The Hammett plot (vs delta Delta G degrees or sigma(+)) is linear for the sulfoniums, but plots for the four pyridinium series have a drastic break between the 4-Cl and 4-NO2 substrates. Broinsted-like plots for the pyridiniums show a strong leaving group effect only for 4-nitrobenzyls. An analysis of these linear free energy relations with supporting evidence from semiempirical computations suggests that collisionally activated pyridinium substrates dissociate by two pathways, direct dissociation and through an ion-neutral complex intermediate. Comparison of these results with results for the solution reactions of some of these compounds shows that the mechanism is different in the gas and solution phases. Sufficient experimental data are not available to assign a mechanism for dissociation to the sulfonium series, but computational results show characteristics of a direct dissociative mechanism.
