PROCESS FOR PREPARING DICARBONYL RHODIUM (I)-BIDENTATE LIGAND COMPLEXES Russian patent published in 1994 - IPC

Abstract RU 2015987 C1

FIELD: synthesis of dicarbonyl rhodium (I)-bidentate ligand complexes having catalytic activity with respect to many organic reactions (hydrogenation, hydroformylation, isomerization, hydroxylation). SUBSTANCE: μ, μ1-dichlorotetracarbonyl rhodium (I) is reacted with protonated bidentate ligand of the formula: HZ wherein Z is a bidentate ligand which is a single-change residue of β-diketones or b-aminovinyl ketones in chloroform at 15-25 C and at a molar ratio of the protonated bidentate ligand to rhodium of (1-1.3): 1. EFFECT: improved process for preparing dicarbonyl rhodium complexes. 1 tbl
