Chlorine-radical-mediated photocatalytic activation of C-H bonds with visible light

Abstract

Going green on the cheap: A highly effective photocatalytic reaction mode involving chlorine radicals generated on chlorinated BiOBr/TiO2 upon irradiation with visible light enabled selective transformations of alkanes into functionalized products through the formation of C-O and C-C bonds (see scheme). This process provides a sustainable strategy for direct C-H functionalization under mild conditions. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
