    Description / Table of Contents: Phosphorus Pentafluoride and Boron Trifluoride in Liquid TrifluoromethanePhosphorus pentafluoride and boron trifluoride form conducting solutions in liquid trifluoromethane. The adducts (CH3)3N·PF5 and (CH3)3N·BF3 and also the salts [(CH3)3NH] [PF6] and [(CH3)3NH][BF4], respectively, may be obtained from these solutions by addition of trimethylamine. Complex anions containing trifluoromethyl ligands are not formed.
    Notes: Phosphor(V)-fluorid bzw. Bor(III)-fluorid zeigen in flüssigem Trifluormethan elektrisches Leitvermögen. Aus den Lösungen lassen sich mit Trimethylamin die Addukte (CH3)3N· PF5 bzw. (CH3)3N·BF3 und die Salze [(CH3)3NH][PF6] bzw. [(CH3)3NH][BF4] gewinnen. Trifluormethylhaltige Komplex-Anionen werden nicht gebildet.

    Description / Table of Contents: Formation of Trifluoromethylated Phosphorofluoridates by Reaction of Trimethyltripuoromethyltin with Phosphorus(V)FluorideReaction of trimethyltrifluorometyltin with phosphorus pentafluoride in an inert solvent affords a solid reaction product. The complex anions [(CF3)2PF4]⊖ and [(CF3PF5]⊖ can be isolated from this reaction product as tetraphenylarsonium salts. The direct bonding of the trifluoromethyl ligands to the phosphorus atom is proved by i. r. and 19F-n. m r. spectra.
    Notes: Durch Umsetzung von Trimethyl-trifluormethylzinn mit Phosphor(V)-fluorid in inertem Lösungsmittel wird ein festes Reaktionsprodukt erhalten, aus welchem die komplexen Anionen [(CF3)2PF4]⊖ und [(CF3PF5]⊖ als Tetraphenylarsoniumsalze isolierbar sind. Die direkte Bindung von Trifluormetyl-Liganden an das Phosphor-Atom kann durch IR- und 19F-Kernresonanzmessung nachgewiesen werden.
