Zusammenfassung
A photoredox-catalyzed procedure for the iodoper-fluoroalkylation of styrenes and phenylacetylenes using readily available copper phenanthroline catalyst is reported. In contrast to commonly employed [Ru(bpy)(3)]Cl-2, [Ru(phen)(3)]Cl-2 or fac-Ir(ppy)(3), [Cu(dap)(2)]Cl is capable to convert styrenes to the corresponding perfluoroalkyl tagged ethylbenzenes, pointing toward an additional role of ...

A photoredox-catalyzed procedure for the iodoper-fluoroalkylation of styrenes and phenylacetylenes using readily available copper phenanthroline catalyst is reported. In contrast to commonly employed [Ru(bpy)(3)]Cl-2, [Ru(phen)(3)]Cl-2 or fac-Ir(ppy)(3), [Cu(dap)(2)]Cl is capable to convert styrenes to the corresponding perfluoroalkyl tagged ethylbenzenes, pointing toward an additional role of the copper catalyst beyond photoinduced electron transfer. An inner sphere catalytic cycle involving Cu(III) intermediates or ligand abstraction from a [Cul](+) intermediate is proposed.
