A new synthetic route to thioacetyl-functionalised 2,2′-bipyridyl complexes

A fast two-step synthetic approach for 4,4′-thioacetyl-functionalised 2,2′-bipyridine is described. Ethylcarbamoyl groups are used as spacers between the sulfur atoms and the pyridyl rings. Both reactions proceed in a highly selective manner. The coordinating properties of the ligand have been assessed.
