Evidence for Asymmetrical Cleavage of Halide-bridged Platinum(II) Complexes by Nucleophiles

The addition of PMe2Ph to at low temperatures produces the ions (1+) and (1-) as major products, as well as some of the expected .It is argued that the ionic species result from two molecules of the attacking nucleophile adding to a single platinum atom of the dimer, instead of the more common symmetrical attack.Less ionic product is produced from the addition of PBu3 to and PMe2Ph to , and none at all was detected from the addition of PBu3 to , so the nature of the phosphines involved has a profound effect on the course of the reactions.The ionic materials are able to undergo rapid phosphine exchange even at -60 deg C if excess ligand (PR3 or Cl-) is present.These exchange reactions can complicate the range of products observed unless precautions are taken to prevent local accumulations of the phosphine in the course of mixing the reactants.
