CATALYTICALLY ACTIVE PERFLUOROCARBOXYLATE COMPOUNDS OF TETRAVALENT PLATINUM Russian patent published in 2015 - IPC C07C51/00 C07C51/41 C07C53/00 C07F15/00 B01J31/04 

FIELD: chemistry.

SUBSTANCE: invention relates to perfluorocarboxylate compounds of tetravalent platinum, characterised by stability in storage without air access. Compounds are obtained by reaction of hydroxo-compound of tetravalent platinum K₂[Pt(OH)₆] or freshly prepared platinum dioxide hydrate PtO₂·4H₂O with perfluorocarboxylic acid R_fCOOH, where R_f=CF₃, C₂F₅, at temperatures from 40 to 70°C for R_f=CF₃ and from 70 to 90°C for R_f=C₂F₅ until homogeneous solution is obtained, with further removal of acid residues in vacuum at temperature not higher than 60°C. Obtained compounds satisfy formula K₂[Pt(R_fCOO)₆] or Pt(R_fCOO)₄. Perfluorocarboxylate compounds of tetravalent platinum of general formula.

EFFECT: M₂[Pt(R_fCOO)₆] (M=Li, K, Na, Rb, Cs, NMe₄) are obtained by heating perfluorocarboxylate of tetravalent platinum Pt(R_fCOO)₄ or platinum dioxide hydrate PtO₂·4H₂O with stoichiometric quantity of salt M(R_fCOO) in respective acid with further removal of its residues in vacuum at temperature not higher than 60°C.

EFFECT: obtained compounds can be used for synthesis of other platinum compounds, for obtaining metal coatings, in homogeneous and heterogeneous catalysis as catalysts and their precursors, as well as initial compounds for obtaining nanosized platinum particles and thereof-based intermetallides
