Electrochemical fluorinations of C(sp )-H bonds with a nucleophilic fluoride source have been accomplished in a chemo- and site-selective fashion, avoiding the use of electrophilic F sources and stoichiometric oxidants. The introduced metal-free strategy exhibits high functional group tolerance, setting the stage for late-stage fluorinations of biorelevant motifs. The synthetic utility of the C(sp )-H fluorination was reflected by subsequent one-pot arylation of the generated benzylic fluorides.
利用亲核氟源对C(sp) -H键进行电化学氟化反应已以化学和位点选择性的方式实现,避免了使用亲电氟源和化学计量的氧化剂。所引入的无金属策略表现出高官能团耐受性,为生物相关基序的后期氟化反应奠定了基础。生成的苄基氟化物随后进行一锅法芳基化反应,体现了C(sp) -H氟化反应的合成实用性。
