• Alkylation of Nitropyridines via Vicarious Nucleophilic Substitution
  作者：Damian Antoniak、Michał Barbasiewicz

  DOI：10.1021/acs.orglett.1c03920

  日期：2022.1.21

  Electrophilic nitropyridines react with sulfonyl-stabilized carbanions to give products of C–H alkylation via vicarious nucleophilic substitution. The process consists of formation of the Meisenheimer-type adduct followed by base-induced β-elimination of the sulfinic acid (e.g., PhSO2H). Mechanistic studies reveal that in the latter step alkyl substituent and adjacent nitro group tend to planarize

  亲电硝基吡啶与磺酰基稳定的碳负离子反应，通过替代亲核取代产生 C-H 烷基化产物。该过程包括形成迈森海默型加合物，然后是碱诱导的亚磺酸（例如，PhSO 2 H）的β-消除。机理研究表明，在后一步中，烷基取代基和相邻的硝基倾向于平面化，以有效稳定苄基阴离子，因此，受阻异丙基碳负离子的加合物由于空间位阻而保持稳定，以消除。

• Alkylation of Nitroarenes via Vicarious Nucleophilic Substitution – Experimental and DFT Mechanistic Studies
  作者：Damian Antoniak、Bartosz Pałuba、Tymoteusz Basak、Kacper Błaziak、Michał Barbasiewicz

  DOI：10.1002/chem.202201153

  日期：2022.8.16

  Alkylation of nitroarenes via Vicarious Nucleophilic Substitution (VNS) was tested experimentally and modelled with DFT calculations. Mechanistic studies reveal intrinsic differences between reactions of archetypal carbanion precursor PhSO2CH2Cl, and alkyl phenyl sulfones, in which benzenesulfinate acts as a leaving group. Accordingly, for the latter precursors steric hindrance develops at the β-elimination

  通过替代亲核取代 (VNS)对硝基芳烃的烷基化进行了实验测试，并使用 DFT 计算进行了建模。机理研究揭示了原型碳负离子前体 PhSO 2 CH 2 Cl 和烷基苯基砜反应之间的内在差异，其中苯亚磺酸盐作为离去基团。因此，对于后者的前体，空间位阻在 β-消除步骤中发展，这会提高能垒并导致副产物的形成。
