(dimethylamino)bis(trifluoromethyl)phosphine and salts of trifluorohydridobis(trifluoromethylphosphate)[(CF3)2PF3H]–, and tetrafluorobis(trifluoromethyl)phosphate ions [(CF3)2PF4]–. 1H and 19F N.m.r. studies confirm the formulae of these novel anions and provide information about their stereochemistry.
二氟化氢钾与氟膦R n PF 3 – n(R = CF 3,n = 0–2)反应,得到含有八面体氟代氢磷酸根阴离子[R n PF 5 – n H] –的盐。也从(a)三氟膦和二甲基甲胺与(b)的反应中获得了五氟氢碘酸氢盐[PF 5 H] –。)(二甲氨基)二氟膦和二氟化氢钾。氟双三氟甲基膦的二甲基氨基水解可提供(二甲氨基)双(三氟甲基)膦和三氟氢双(三氟甲基磷酸)[(CF 3)2 PF 3 H] –和四氟双(三氟甲基)磷酸根离子[(CF 3)2 PF 4 ] –的盐。。1 H和19 F Nmr研究证实了这些新型阴离子的分子式,并提供了有关其立体化学的信息。
