FIELD : chemistry of organophosphorus compounds, chemical technology. SUBSTANCE : invention describes a method for synthesis of monohydroperfluoroalkanes, bis-(perfluoroalkyl)phosphinates and perfluoroalkylphosphonates. Method involves treatment of at least one perfluoroalkylphosphorane with at least one base wherein base(s) are chosen from group consisting of alkali-earth metal hydroxides, metalloorganic compound in useful solvent or at least one organic base and an acid in useful reaction medium. Also, invention describes novel perfluoroalkylphosphonates and bis-(perfluoroalkyl)phosphinates, using novel perfluoroalkylphosphonates and bis-(perfluoroalyl)phosphinates as ionic liquids, catalysts of phase transfer or surfactants. EFFECT : improved method of synthesis. 18 cl, 19 ex
