Abstract

Dimethyl formamide (DMF) can be a convenient source of the carbonyl ligandin the coordination chemistry of rhodium, ruthenium, iridium, and platinum. We have undertaken a thorough study concerning the course of this reaction. In a first step, DMF-containing complexes are produced, which is usuallyaccompanied by chloride redistribution. Then, upon refluxing, carbonyl species in the same oxidation state are obtained, presumably as a result of HCl-mediated DMF decomposition. Provided that water levels are kept low, reduction can occur to provide the complexes [NH2(CH3)(2)][RhCl2(CO)(2)], [NH2(CH3)(2)][RuCl3(CO)(2)(DMF)], [RuCl2(CO)(2)(DMF)(2)], and [NH2(CH3)(2)][IrCl2(CO)(2)]. In the case of platinum, reduction is not effective and [NH2(CH3)(2)][PtCl3(CO)] is obtained. No carbonylpalladium species can be synthesized in this way, the reaction producing copious amounts of colloidal metal. Adding phosphanes to these chlorocarbonyl-containing solutions allows easy,one-step syntheses of a variety of complexes.
