Process for the preparation of platinum acetylacetonato complexes

Abstract

Preparation of halogenide-free Platinum(II)acetylacetonate [Pt(acac)2] Platinum(II) hexafluoroacetylacetonate [Pt(hfac)2], Platinum(II) trifluoroacetylacetonate [Pt(tfac)2] or Platinum(II)-alkylsubstituted acetylacetonates by the reaction of a halogen free platinum (IV) oxo- or hydroxo-compound, such as PtO2.nH2O (n being an integer from 1 to 4) or H2Pt(OH)6 or Na2Pt(OH)6 or K2Pt(OH)6, with a reducing agent in aqueous solution in the presence of a stoichiometric or higher amount of acetylacetone (acac), potassium acetylacetoante (Kacac) sodium acetylacetonate (Naacac), hexafluoroacetylacetone (hfac), trifluoroacetylacetone (tfac) or alkyl substituted acetylacetones or their salts and an H+ donor.
