Abstract: The present invention is directed to methods for the preparation of (CnF2n+1)O-substituted arenes and heteroarenes and the direct perfluoralkoxy lation of arenes and heteroarenes with a (CnF2n+1)O-group, respectively. characterized in that a peroxide reagent according to the general formula (I): (CnF2n+1)2 (I) is fragmented in the presence of an electron transferring catalyst under (CnF2n+1)O-radical formation, and said (CnF2n+1)O-radical then substitutes a C—H bond of an arene or heteroarene C—H bond with a (CnF2n+1)O-group, wherein in the above formulae, n is an integer in the range from 1 to 4.
