  Electrochemical fluorination of trialkylphosphines

  摘要：

  The electrochemical fluorination (ECF) of trialkylphosphines results in the formation of the corresponding tris(perfluoroalkyl)difluorophosphoranes in good yield. In the case of ECF of tri(iso-butyl)phosphine, isomerisation of iso- into n-alkyl compound occurs. (C) 2000 Elsevier Science S.A. All rights reserved.

  Michael addition catalyzed by difluorotris(pentafluoroethyl)phosphorane

  摘要：

  Difluorotris(pentafluoroethyl)phosphorane, (C2F5)(3)PF2, was found to be an active catalyst for the Michael addition reaction of 1,3-beta-diketones or beta-ketoesters (Michael donors) and linear or cyclic unsaturated ketones (Michael acceptors). The reaction proceeds under mild conditions with low catalyst loading and results in the formation of the Michael addition products in moderate to high yields. The developed protocol does not require the use of a base for the in situ generation of a carbanion (Michael donor). (C) 2015 Elsevier B.V. All rights reserved.

  Fluoride ion affinities (FIA), provided by DFT calculations, are exceedingly useful for the design of new Lewis acids with defined reactivities. Herein, we report the synthesis, characterization and reactivity of new difluoro(perfluoroorganyl) phosphoranes, which readily abstract fluoride ions from di-fluoro(triorganyl)phosphoranes. Highly reactive fluorobismuthonium cations and the [Ph3Bi(NCCH3)(2)](2+)

  liquids exhibit excellent hydrolytic stability, low viscosity and high electrochemical and thermal stability. Organic and inorganic salts with FAP anions possess high electrochemical stability and conductivity that makes them attractive for application in several electrochemical devices (Li-ion batteries, super-capacitors, etc.). The possible application of H[(RF)3PF3] (HFAP), (RF)2P(O)(OH) and (RF)P(O)(OH)2
