Synthesis, characterization and exploration of the catalytic, supramolecular and biological applications of dinuclear complexes

Johnpeter, Justin Paul Raj ; Therrien, Bruno (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2013.

The work presented in this thesis involves the synthesis and characterization of dinuclear ruthenium, rhodium and iridium complexes. The catalytic, supramolecular and biological applications of these dinuclear complexes will be discussed. In the first part, the synthesis of sawhorse-type diruthenium tetracarbonyl complexes and their catalytic applications in the supercritical carbon dioxide...
