Carbonyl Complexes of rhodium(I) with β-diketones

799-800Dicarbonyl β-diketonatorhodium(I) complexes of the type [Rh(CO)2(LL)] (LL = β-diketonate) have been prepared. [Rh(CO)2(LL)] reacts with PPh3 or AsPh3 to give rise to complexes of the type [Rh(CO)(LL)L'] (L' = PPh3 or AsPh3) by the replacement of one of the CO groups by PPh3 or AsPh3. All the complexes have been characterized by elemental analyses, and IR and electronic spectral data
