Perfluoroalkyl compounds are persistent environmental
pollutants
due to their chemical and thermal stability. Hydrodefluorination is
one of the most promising strategies for the disposal of fluorine-containing
compounds, which has attracted much attention from a broad spectrum
of scientific communities. Herein, we disclose a metal-free, visible-light-promoted
protocol for the exhaustive hydrodefluorination of a wide variety
of trifluoromethylarenes with up to 95% yields. Moreover, methyl-d3 groups can be obtained
via deuterium water with a D ratio of up to 94%.
