  Bi(V)氟化物形成芳基-F键的机理

  摘要：

  在本文中，我们描述了中性和阳离子高价有机铋(V)氟化物形成C(sp 2 )–F键的联合实验和理论机理研究，其特征是双阴离子双芳基亚磺酰亚胺配体。对配体、亚磺酰亚胺和中性二氟化三芳基铋(V)上的反应性芳基的取代模式的详尽评估表明，溶液中二聚结构的形成促进了Ar-F键的容易形成。值得注意的是，中性二氟化铋（V）还原消除的理论模型与实验确定的动力学和热力学参数一致。此外，添加外部氟化物源会产生无活性的八面体阴离子三氟化铋盐，从而减缓还原消除。另一方面，对阳离子氟化铋的平行分析揭示了四氟硼酸根阴离子作为氟化物源的关键作用。实验和理论分析都得出结论，C-F 键的形成是通过低能五元过渡态途径发生的，其中 F 阴离子从 BF 4阴离子传递到 C(sp 2 ) 中心，让人想起巴尔兹-希曼反应。在整个研究过程中收集的知识可以对几种配体的关键参数进行合理评估，确定简单的基于砜的配体家族作为芳基硼酸衍生物化学计量和催化氟化的改进系统。

  N-Trifluoromethylthiolated Sulfonimidamides and Sulfoximines: Anti-microbial, Anti-mycobacterial, and Cytotoxic Activity

  摘要：

  Herein we demonstrate the expanded utility of a recently described N-trifluoromethylthiolation protocol to sulfonimidamide containing substances. The novel N-trifluoromethylthio sulfonimidamide derivatives thus obtained were evaluated for antibacterial activity against Mycobacterium tuberculosis (M. tb.) and Mycobacterium abscessus and Gram + Ve (Streptococcus aureus, Bacillus subtilis), and Gram - Ve (Escherichia coli, Pseudomonas aeruginosa) bacteria. Two compounds, 13 and 15 showed high antimycobacterial activity with MIC value of 4-8 mu g/mL; i.e. comparable to WHO recommended first line antibiotic for TB infection ethambutol. The same compounds were also found to be cytotoxic in HepG2 cells (compound 13 IC50 = 15 mu g/mL; compound 15 IC50 = 65 mu g/mL). A structure activity relationship, using matched pair analysis, gave the unexpected conclusion that the trifluoromethylthio moiety was responsible for the cellular and bacterial toxicity. Given the increasing use of the trifluoromethylthio group in contemporary medicinal chemistry, this observation calls for considerations before implementation of the functionality in drug design.

  An unprecedented approach to N-trifluoromethylations of electron-rich nucleophilic sites following a radical pathway is reported. Accordingly, various sulfoximines (19 examples) have been N-trifluoromethylated, providing previously unreported products with satisfying functionality tolerance in moderate to good yields. With a C-N bond length at the N-CF3 moiety of 1.341 angstrom the respective linkage is shorter than a traditional C-N single bond and comparable with that of a C-N double bond.

  organobismuth(V) fluorides, featuring a dianionic bis-aryl sulfoximine ligand. An exhaustive assessment of the substitution pattern in the ligand, the sulfoximine, and the reactive aryl on neutral triarylbismuth(V) difluorides revealed that formation of dimeric structures in solution promotes facile Ar–F bond formation.
