The work herein demonstrates the viability of an electrochemical oxidative protocol for the expedient realization of 1,3-fluorofunctionalization of arylcyclopropanes under catalyst- and oxidant-free conditions. Given the relatively low nucleophilicity of fluoride ion, the counterintuitive outcome that the ring-opening is initiated by nucleophilic fluorination is rationalized by invoking tight ion pair
本文的工作证明了电化学氧化方案在无催化剂和无氧化剂条件下快速实现芳基环丙烷 1,3-氟官能化的可行性。鉴于氟离子相对较低的亲核性,通过调用芳基阳离子和BF 4 - 抗衡离子之间的紧密离子对,可以合理地解释由亲核氟化引发开环这一违反直觉的结果。通过整合醇、酸和 N-杂环作为终止亲核试剂,可以顺利实现直接的 1,3-氟氧化和 1,3-氟胺化。
