Preparation and spectroscopic characterization of difluorophosphorane, PH3F2. 31P NMR spectrum of protonated diphosphine, P2H5+

The preparation of difluorophosphorane, PH3F2, from the reaction of diphosphine and hydrogen fluoride is reinvestigated; it has been characterized by multinuclear (1H, 19F, 31P) NMR spectroscopy. Complete infrared and Raman low-temperature spectra of difluorophosphorane are reported. It reacts with alkali-metal fluorides to give phosphine and hexafluorophosphates(V). On the basis of 31P NMR spectroscopic results, a reaction mechanism for the formation of PH3F2 is proposed. The byproducts of the reaction were PH2F3, (PH)n, and P2H5+; the last was observed for the first time. In carbon disulfide solution, diphosphine neither reacts with hydrogen halides to yield protonated diphosphine nor interacts with hydrogen fluoride to form difluorophosphorane.
