Fluoroalkylsulfonyl chlorides, RfSO2Cl, in which Rf=CF3, C4F9, CF2H, CH2F, and CH2CF3, are used as a source of fluorinated radicals to add fluoroalkyl groups to electron‐deficient, unsaturated carbonyl compounds. Photochemical conditions, using Cu mediation, are used to produce the respective α‐chloro‐β‐fluoroalkylcarbonyl products in excellent yields through an atom transfer radical addition (ATRA) process
氟烷基磺酰氯,R f SO 2 Cl,其中R f= CF 3,C 4 F 9,CF 2 H,CH 2 F和CH 2 CF 3,被用作氟自由基的来源以向电子中添加氟烷基。不足的不饱和羰基化合物。通过铜介导的光化学条件,可通过原子转移自由基加成(ATRA)工艺以优异的产率生产相应的α-氯-β-氟代烷基羰基产物。α-氯取代基的容易亲核取代会导致产物进一步多样化的功能。
