METHOD OF PREPARING COMPLEX TRANS-DIBROMOTETRAKIS(DIMETHYLSULFOXIDE)RUTHEN IUM(II) Russian patent published in 2004 - IPC

Abstract RU 2230035 C1

FIELD: coordination compounds chemistry. SUBSTANCE: title compound depicted by formula trans-[Ru(DMSO)₄Br₂], finding use as catalyst, bioactive preparation, and starting material for synthesis of various ruthenium compounds, is prepared by dissolving ruthenium bromide in dimethylsulfoxide on heating, using, as ruthenium bromide precursor, sodium nanobromodiruthenate(III). Heating is carried out on water bath for 24-45 min. Precipitate os filtered, washed with acetone, and dried to constant weight. EFFECT: increased yield of product to 80% and simplified synthesis procedure. 1 tbl
