Single defluorination of aryl polyfluoromethyl functionalities is achieved by both intra- and intermolecular silylium cation/phosphine Lewis pairs. Phosphine-captured aryl fluoromethyl cations are then treated with Bronsted base to complete the first mono-hydrodefluorinations of PhCF3, Ph2CF2, and PhCF2.
