terminal alkynes driven by the noncovalent interaction between a thymol anion and fluoroalkyl iodides. By precisely tuning the reaction solvent, a wide range of 37 structurally diverse perfluoroalkylated alkynes and alkenes, including ibuprofen, empagliflozin, galactose, isoxepac and indomethacin, were obtained in up to 92% yields. Mechanistic studies reveal the formation of EDA complexes between the
在此,我们报道了由百里酚阴离子和氟烷基碘之间的非共价相互作用驱动的末端炔烃的光诱导选择性全氟烷基化。通过精确调节反应溶剂,获得了 37 种结构不同的全氟烷基化炔烃和烯烃,包括布洛芬、恩格列净、半乳糖、异氧派和吲哚美辛,收率高达 92%。机理研究揭示了百里酚阴离子和氟烷基碘之间形成 EDA 复合物。该策略可以为制备有用的全氟烷基化炔烃和烯烃的传统方法提供重要的补充。
