Abstract
The anionic complexes [RhCl2(CO)(2)](-), [IrCl2(CO)(2)](-) or [RuCl3(CO)(2) (DMF)](-) can be obtained in high yields (up to 85 %) and in less than GO m in by refluxing dimethylformamide solutions of RhCl3. 3H(2)O, IrCl3. 3H(2)O or RuCl3. 3H(2)O. Depending on the metal, the presence of small amounts of water and/or hydrochloric acid greatly accelerates the reduction step. For rhodium, several intermediates have been trapped which allow us to propose a mechanism for this reaction. (C) Academic des sciences/Elsevier, Paris.
