Fluorophosphonate and alkoxy- and aroxy-fluorophosphine complexes of platinum(II) and palladium(II). Part I. Reactions of complexes of tertiary phosphines with alkoxy- and aroxy-difluorophosphines

Abstract

A series of difluorophosphonato-complexes trans-[MClL₂(PF₂O)](M = Pt or Pd; L = PEt_{3 –n}Ph_n; n= 0–3) have been prepared via a Michaelis–Arbuzov type reaction from [MCl₂L₂] and PF₂(OR)(R = allyl, Prⁿ, or Buⁿ). Preparation of complexes cis-[MCl₂(PEt₃){PF₂(OR)}](M = Pt or Pd; R = Buⁿ or Ph) and chloro-bridged binuclear complexes [{MCl(PEt₃)(PF₂O)}₂] is also reported. Substituent redistribution reactions of PF₂(OR) have been observed under the influence of the transition metal, M. Fluorine-19 and ³¹P n.m.r., i.r., and, in part, mass-spectroscopic data for the new complexes are reported and discussed in terms of the structures of the products obtained.
