Abstract The synthesis and reactivity of an air water stable Bicyclic (alkyl)(amino)carbene (BICAAC) stabilized phosphenium cation (1) is reported. Air are rare in the literature. Compound 1 obtained by reaction BICAAC with Ph 2 PCl THF followed anion exchange LiOTf. reduction oxidation yielded corresponding α‐radical phosphine species (2) oxide (3) respectively. All compounds well characterized single crystal X‐ray diffraction studies. Lewis acidity 3 determined conducting fluoride ion affinity experiments using UV‐Vis spectrophotometry multinuclei NMR spectroscopy. Compounds exhibited selective binding to but did not interact other halides (Cl − Br ). Quantum chemical calculations were performed understand structure nature bonding interactions these compounds, as comprehend specific over halide ions.
