An iron-catalyzed aryldifluoromethylation of activatedalkenes under mild reaction conditions has been developed, which is a rare example where a cosolvent is used to improve the reaction yield along with Fenton's reagent and thus provides an economic and green method for the synthesis of a variety of difluoromethylatedoxindoles. Preliminary mechanistic investigations indicate a radical addition path
