  Synthesis of Non-Symmetric Functionalized Polyfluoroalkyl Phosphites

  摘要：

  Two ways for the synthesis of new representatives of non-symmetric organic phosphites with polyfluoroalkyl substituents were developed based on organic dichlorophosphites. The reaction of polyfluoroalkyl dichlorophosphites with allyl alcohol, proceeding at a temperature of -10-22 degrees C (2 h) in the presence of triethylamine, gave diallyl polyfluoroalkyl phosphites in a yield of 75-77%. Under similar conditions (-30-22 degrees C, 2-4 h, Et3N), alkyl (or aryl) dichlorophosphites reacted with polyfluoroalkanols to form alkyl (or aryl) bis(polyfluoroalkyl) phosphites (yield 56-67%). Unlike diallylpolyfluoroalkyl- and alkylbis(polyfluoroalkyl) phosphites, arylbis(polyfluoroalkyl) phosphites are symmetrized under storage conditions (room temperature, inert atmosphere), forming the corresponding triaryl- and tris(polyfluoroalkyl) phosphites.

  Processes and reaction mixtures including non-aqueous solvent mixtures are presented. Non-aqueous solvent mixtures including fluoride salt and non-aqueous solvent combinations are provided that possess high fluoride ion concentrations useful for a range of applications, including organic synthesis. Further non-aqueous solvent mixtures are provided including a salt possessing a non-fluoride anion and a non-aqueous solvent that, when contacted with aqueous fluoride-containing reagents, extract fluoride ions to form non-aqueous fluoride-ion solutions possessing high fluoride-ion concentrations. The salts include an organic cation that does not possess a carbon in the β-position or does not possess a carbon in the β-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. The combination of these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents.

  提供了包括非水溶剂混合物的过程和反应混合物。提供了包括氟化物盐和非水溶剂组合的非水溶剂混合物，其具有高氟离子浓度，可用于一系列应用，包括有机合成。还提供了包括具有非氟离子的盐和非水溶剂的非水溶剂混合物，当与含氟化物的水溶试剂接触时，提取氟离子以形成具有高氟离子浓度的非水溶性氟离子溶液。这些盐包括一个有机阳离子，该阳离子在β位不含碳或在β位含有结合氢的碳。这种盐的结构有助于使其在无水条件下不分解。例如，无水氟化物盐包括(2,2-二甲基丙基)三甲基铵氟化物和双(2,2-二甲基丙基)二甲基铵氟化物。这些氟化物盐与至少一种含氟非水溶剂（例如双(2,2,2-三氟乙基)醚；(BTFE)）的组合促进了盐在非水溶剂中的溶解度。

  Electrolyte solutions including at least one anhydrous fluoride salt and at least one non-aqueous solvent are presented. The fluoride salt includes an organic cation having a charge center (e.g., N, P, S, or O) that does not possess a carbon in the β-position or does not possess a carbon in the β-position having a bound hydrogen. This salt structure facilitates its ability to be made anhydrous without decomposition. Example anhydrous fluoride salts include (2,2-dimethylpropyl)trimethylammonium fluoride and bis(2,2-dimethylpropyl)dimethylammonium fluoride. Combining these fluoride salts with at least one fluorine-containing non-aqueous solvent (e.g., bis(2,2,2-trifluoroethyl)ether; (BTFE)) promotes solubility of the salt within the non-aqueous solvents. The solvent may be a mixture of at least one non-aqueous, fluorine-containing solvent and at least one other non-aqueous, fluorine or non-fluorine containing solvent (e.g., BTFE and propionitrile or dimethoxyethane). The electrolyte solutions may be employed in electrochemical cells, such as batteries, fuel cells, electrolysis systems, and capacitors.
