Light Induced Catalytic Hydrodefluorination Of Perfluoroarenes By Porphyrin Rhodium

Fluorine-containing organic compounds are essential building blocks that have been extensively employed in materials chemistry, medicinal chemistry as well as agrochemistry.(1) Simple perfluorinated bulk chemicals are easily accessible on an industrial scale, whereas the selective cleavage of C-F bonds of perfluorinated compounds is regarded as a promising approach to access partially fluorinated compounds.(1d-h) However, this defluorination process has been considered as one of the greatest challenges for synthetic chemistry due to the relative inertness of the C-F bond.(2)
