Thermolysis of Tetranuclear Palladium Clusters: Unexpected Transfer of Oxygen from a Carboxylate Group to Carbene and Carbonyl Bridging Ligands; Carbon Dioxide Insertion into C H Bonds

Thermolysis of the tetranuclear palladium clusters [Pd 4(μ-Q) 4(μ-O 2CR) 4] (Q = CPh 2 or CO; R = Me, CMe 3, Ph, CH 2Cl or CF 3) has been found to involve inner-sphere oxidation of carbene or carbonyl ligands during which an oxygen atom transfer occurs from the carboxylate group to the carbene or ca...

Description
Summary:Thermolysis of the tetranuclear palladium clusters [Pd 4(μ-Q) 4(μ-O 2CR) 4] (Q = CPh 2 or CO; R = Me, CMe 3, Ph, CH 2Cl or CF 3) has been found to involve inner-sphere oxidation of carbene or carbonyl ligands during which an oxygen atom transfer occurs from the carboxylate group to the carbene or carbonyl ligand; the thermolysis of the carbonyl clusters gives rise to the products of CO 2 insertion into the C H bond of benzene or toluene used as solvents forming benzoic acid from benzene and a mixture of phenylacetic and toluic acids from toluene.
