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.
A rapid synthetic procedure has been devised for the preparation of a doubly thioacetyl-functionalised bipyridine-based ligand which involves the transformation of 4,4′-dimethyl-2,2′-bipyridine into an activated diester whose electrophilicity shows high amine over thiol preference. Subsequent reaction with appropriate transition metal precursors afforded both homo- and heteroleptic tris(bipyridine)-type octahedral complexes.Figure optionsDownload as PowerPoint slide
