METHOD OF PRODUCING HETERONUCLEAR ACETATE COMPLEXES OF DIVALENT PLATINIC Russian patent published in 2018 - IPC C07C53/10 C07C51/41 C07F19/00 B01J31/22 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing of heteronuclear acetate complexes of divalent platinic. Method consists in the fact that to the aqueous caustic of hydroxoplatinate alkali metal is added under stirring aqueous caustic of salt of divalent metal M, selected from a number of M = Ca, Sr, Ba, Ni, Co, Mn, Cu, Zn, Cd, Pb, non-water-soluble gel of hydroxoplatinete MPt (OH)_6th is obtained, which is boiled in excess of glacial acetic acid until completely dissolved, then the solvent is removed in vacuo at temperature of 60–80 °C, and the obtaining slimy mass is held in vacuum desiccator over alkali until it is completely setting solid. Solid mass is dissolved in methylene chloride or chloroform, the solution is filtered, the solvent is removed in vacuum and recrystallization from acetic acid is made. Heteronuclear complexes are obtained MPt(CH₃COO)₄⋅xCH₃COOH⋅yH₂O, where x is 1, 2 and 4, and y is 0, 1, and 2.

EFFECT: invention allows to obtain stable acetated compounds of platinum in efficiency of 90–98 %, soluble in polar solvents and suitable for use in catalysis of oxidation of organic compounds and for production of mononuclear acetate complexes Pt(II).
