Abstract
Carbon monoxide reacts with dimethylacetamide solutions of RhCl3,3H2O under mild conditions to give initially a monocarbonyl complex of rhodium(III) in a bimolecular SN2 reaction. This complex is slowly decomposed by the water present from the trihydrate to give the dichlorodicarbonylrhodate(I) species, [Rh(CO)2Cl2]–. The study gives direct evidence for the role of water, or more likely hydroxide, in the reduction of metal ions by carbon monoxide.Keywords
