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 = PEt3 –nPhn; 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.
