Castelli, Ugo published the artcileEvidence of Phosphonium-Carbenium Dication Formation in a Superacid: Precursor to Fluorinated Phosphine Oxides, Quality Control of 4141-48-4, the publication is Angewandte Chemie, International Edition (2019), 58(5), 1355-1360, database is CAplus and MEDLINE.
Unambiguously confirmed by low-temperature in situ NMR experiments, x-ray diffraction and vibrational spectroscopy, phosphonium-carbenium superelectrophiles are generated in strong acidic conditions. Representing crucial intermediates, their exploitation allows for the synthesis of unprecedented fluorinated (cyclic) phosphine oxides.
