developed a generic protocol that allows a single substitution of one fluoride in trifluoromethylgroups with neutral phosphine and pyridine bases. The resulting phosphonium and pyridinium salts can be further functionalized via nucleophilic substitution, photoredox coupling and electrophilic transfer reactions allowing the generation of a vast array of difluoromethyl products.
