Synthese und Eigenschaften von Pentafluorophosphaten,YPF5− (Y = OR,NHAr), und PF5 · Amin-Addukten,PF5 · HNR2

Synthesis and Properties of Pentafluorophosphates, YPF₅^? (Y = OR, NHAr), and PF₅-Amine Adducts, PF₅ · NHR₂ In the presence of secondary amines instead of hexafluorophosphates, PF₆^?, PF₅-amine adducts, PF₅ · NHR₂, are obtained by the reaction of PCl₅ with alkylammonium fluorides in acetonitrile. The additional presence of alcohols or phenol leads to the formation of alkoxy- or aroxypentafluorophosphates, ROPF₅^?. The PF₅-amine adducts can be converted into ROPF₅^? or arylimidopentafluorophosphates, ArNHPF₅^?, resp., by treating with alcohols or aryl amines, resp.
