Hydrofluoroethers are shown to alkylate tertiary amines readily under solvent‐free conditions, affording valuable tetraalkylammonium perfluoroalkoxides bearing α‐fluorines. The reaction of RFCF2OCH3 (RF=CF2CF3, CF2CF2CF3, and CF(CF3)2) with NR1R2R3 produces twenty new α‐perfluoroalkoxides, [(CH3)NR1R2R3][RFCF2O] under mild conditions. These α‐perfluoroalkoxides are easy to handle, thermally stable
氢氟醚在无溶剂条件下很容易使叔胺烷基化,从而提供了有价值的带有α-氟代的四烷基铵全氟烷氧化物。的R中的反应˚F CF 2 OCH 3(R ˚F = CF 2 CF 3,CF 2 CF 2 CF 3,和CF(CF 3)2)与NR 1 - [R 2 - [R 3产生20新α-perfluoroalkoxides,[( CH 3)NR 1 R 2 R 3 ] [R F CF 2O]在温和的条件下。这些α-全氟烷氧化物易于处理,热稳定,可用于苄基溴的全氟烷氧基化。
