METHOD OF PREPARING RHODIUM (III) AND IRIDIUM (III) BETA- DIKETONATES Russian patent published in 1998 - IPC

FIELD: non-ferrous metallurgy, more particularly preparation of volatile rhodium and iridium complexes. SUBSTANCE: claimed method comprises using complex fluorides of said metals in oxidation state (III). Said complexes are produced by reaction of fusion of hexanitrites thereof with mixture of potassium hydrofluoride and acid at certain ratio as original compounds for reaction with beta-retones under appropriate conditions. Amounts of original compounds, cheap reagents, standard equipment and few operations make it possible to simplify method of preparing rhodium and iridium beta-diketonates and retain high yield thereof. EFFECT: more efficient preparation method. 3 cl
