Patent ID: 7442820

Claim:
A process for the production of halogenide-free Platinum(II)acetylacetonate [Pt(acac) 2 ] or Platinum(II) hexafluoroacetylacetonate [Pt(hfac) 2 ] or Platinum(II) trifluoroacetylacetonate [Pt(tfac) 2 ] or Platinum(II)-alkylsubstituted acetylacetonate, wherein I. a halogen free platinum (IV) oxo- or hydroxo-compound is reacted with II. a reducing agent III. in aqueous solution in the presence of IV. a stoichiometric or higher amount based on platinum (IV) of acetylacetone (acac), hexafluoroacetylacetone (hfac), trifluoroacetylacetone (tfac) or alkyl substituted acetylacetonate or their salts and V. a H + donor.
