Abstract:
The first palladium carbene cluster, μ-tetrakis(diphenylmethyliden)-μ-tetraacetato-quadro-tetrapalladium (4Pd-Pd) Pd4(μ-CPh2)4(μ-OAC)4 (I), has been synthesized by substitution of diphenylcarbene ligands for CO-groups in μ-tetrakis(carbonyl)-μ-tetraacetato-quadro-tetrapalladium (4Pd-Pd) Pd4(μ-CO)4(μ-OAc)4 (II) and characterized with EXAFS data. Reactivity of I, II and related clusters is discussed. Thermolysis of the clusters has been found to involve inner-sphere oxidation of carbene or carbonyl ligands during which an oxygen atom is transferred from the carboxylate group to the carbene or carbonyl ligand. Thermolysis of carbonyl clusters in benzene or toluene solutions gives rise to the products of CO2 insertion into the C-H bond of the solvent forming benzoic acid from benzene and a mixture of phenylacetic and tolyl acids from toluene.
