Abstract
Carbonylation of [Rh(COD)N3]2 (COD = 1, 5-cyclooctadiene) in ethanol gave the rhodium cluster [Rh6(CO)16] selectively in high yield; when non polar solvents were used, the known [Rh(CO)2N3]2 and [Rh(CO)2NCO]2 were obtained. Reaction of carbon monoxide with the isocyanato-bridged derivative [Rh(CO)2NCO]2 in ethanol also gave [Rh6(CO)16]. In both cases the carbonylation reaction also gave NH2COOEt. Carbonylation of the iridium dichloride dimer [Ir(COD)Cl]2 in the presence of sodium citrate gave [Ir4(CO)12].
