The present invention relates to a chlorotrifluoromethylation method of an alkene compound using a photoredox catalyst and CF_3SO_2Cl. According to the present invention, the chlorotrifluoromethylation method of an alkene compound only generates SO_2 as a byproduct with one step of reaction and provides a source of -Cl and -CF_3 which are significant functional groups in pharmaceutical chemistry at the same time while having excellent regioselectivity of substituting -Cl to the carbon with a higher order.(AA) Time(BB) Conversion by ^1H NMR(%)COPYRIGHT KIPO 2016

Photoredox-catalyzed vicinal chlorotrifluoromethylation of alkene is described. In the presence of Ru(Phen)3Cl2, CF 3SO2Cl was used as a source for the CF3 radical and chloride ion under visible light irradiation. Various terminal and internal alkenes were transformed to their vicinal chlorotrifluoromethylated derivatives. Biologically active compounds were applied under the condition to obtain desired products, suggesting that the method could be feasible for late-stage modification in drug discovery.
