Abstract

An efficient metal-free, photomediated iodo perfluoroalkylation under mild conditions was developed. Using catalytic amounts (10 mol %) of phosphines and blue light irradiation, various olefins are transformed into the corresponding addition products within short reaction times. For this purpose, a modular and convenient 3D printed photoreactor was constructed, which is presented as an open source model. The reaction presumably proceeds upon generation of perfluoroalkyl radicals, which are formed by catalyst-induced absorption enhancement.
