Photoinduced, copper-catalysed direct perfluoroalkylation of heteroarenes

Abstract

An efficient and general process is reported for the photoinduced, copper-catalysed direct perfluoroalkylation of C–H bonds in a broad range of heteroarenes with commercially available perfluoroalkyl iodides. This redox neutral process is simply based on the use of [Cu(bcp)DPEPhos]PF₆ as the photoredox catalyst in the presence of potassium acetate and smoothly operates at room temperature.
