• 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。
