Tri(phosphonio)methanide dication32+, prepared from a trifluoromethylsulfanylphosphonium dication (12+) via an intramolecular electrophilic aromatic substitution reaction, is an unexpected P‐based, water‐resistant Lewis acid that is capable to selectively and reversibly bind fluoride ions from organic/aqueous biphasic solution. The formed complex is an unusual fluorophosphorane ([3‐F]OTf). The multiple donor–acceptor interactions of32+that are crucial for the fluoride fixation have been elucidated by quantum chemical calculation. Compound[3‐F]OTf can also be used as a convenient anhydrous fluoride ion source and was probed as a suitable catalyst of the silylotrifluoromethylation of various aldehydes.
