Abstract: An efficient copper-catalyzed direct C(sp2)-H/C(sp3)-H coupling reaction of aza-aromatic rings with fluoroalcohols is developed. A variety of useful building blocks including hydroxyfluoroalkylated aniline, pyrrole, and indole derivatives bearing a quaternary carbon center could be constructed…

Abstract: Photoredox-catalyzed direct C(sp2)-H difluoromethylation of enamides is accomplished by using easily accessible [bis(difluoroacetoxy)iodo]benzene as the CF2H source. Diverse (E)-β-difluoromethylated enamides are obtained in moderate to good yields by using this...
