ORGANOPHOSPHORUS CHEMISTRY. PART 21. INSERTION OF OLEFINS INTO P-CF3 BONDS

Tris(trifluoromethyl)phosphine and ethylene reacted efficiently under u.v. irradiation to give 3,3,3-trifluoropropylbis(trifluoromethyl)phosphine in good yield.With vinyl fluoride, vinylidene fluoride, and propene the reaction was regioselective rather than regiospecific, and the yield of 1:1 adduct was low.In these reactions, and in those with vinyl chloride, but-1-ene, and hexafluoropropene, in which only traces of 1:1 adduct could be detected, the bulk of the olefin and of the phosphine was recovered, and numerous by-products consistent with radical intermediates were identified.With propyne, 1,1,1-trifluoro-3-bis(trifluoromethyl)phospino-cis-but-2-ene was obtained in moderate yield, but no reaction occured between the phosphine and either but-2-yne or hexafluorobut-2-yne.Tris(trifluoromethyl)phosphine oxide did not form an adduct with ethylene, tetrafluoroethylene, or propyne.Bis(trifluoromethyl)phosphine and dimethylphosphine both reacted readily under u.v. irradiation with 3,3,3-trifluoropropene, the phosphinyl radical attacking the terminal carbon in each case.

The phosphorus-phosphorus bond. II. The preparation and characterization of phosphinodifluorophosphine, H2PPF2, bis(trifluoromethyl)phosphinodifluorophosphine, (CF3)2PPF2, and their borane adducts, H2PPF2·BH3 and (CF3)2PPF2·BH3

Conditions have been found for a high-yield preparation of phosphinodifluorophosphine, H2PPF2, from an excess of PH3 with F2PPF2 in the presence of small amounts of F2PI. Bis(trifluoromethyl)phosphinodifluorophosphine, (CF3)2PPF2, has been prepared with a Wurtz-like coupling of F2PI and (CF3)2PI or by a redistribution reaction involving F2PPF2 and (CF3)2PP(CF3)2. Coordination of BH3 to the PF2 site in both diphosphines is preferred; neither H2PPF2 nor (CF3)2PPF2 was found to coordinate two BH3 groups. The new unsymmetrical diphosphines and their borane adducts have been characterized by nmr (1H, 19F, 31P, and 11B), ir, Raman, mass spectroscopy, and vapor density. The facile vapor-phase dissociation of the borane adducts precluded determination of their vapor pressure curves but such data are given for the parent diphosphines.
