Studies Of The Chemistry Of Pentaruthenium Carbido Carbonyl Cluster Complexes With Aldehydes, Azobenzene And Alkynes, Humaiara Akter

Theses and Dissertations

Polynuclear metal carbonyl complexes serve as the bridging model between heterogeneous catalysis and homogeneous catalysis for the activation of small molecules. Ru5(m5-C)(CO)15 has been found to exhibit superior reactivity due to its unusual polynuclear metal geometry. possibilities of interconversions of ligand bonding modes, and the formation of the electronically unsaturated metal species. C-H activation in aldehydes and azobenzene of pentaruthenium cluster complexes is described in chapters 2 and 3 respectively. The formation of new hydrocarbyl zwitterions and C – C coupling ethyne to the carbido carbon in the complex, and the alkyne insertion reactions with pentaruthenium cluster complexes are described …
