| Abstract: | Three cognate ligands containing bipyridine carboxylic frameworks were readily prepared under mild conditions from a pivotal 6-bromo-6'-bromomethyl-2,2'-bipyridine building block and a primary amine as starting materials. In one case, the amine was adequately functionalised with a nitro group. Transformation of the resulting bromo derivatives to the corresponding ethyl esters was made possible by the use of a carboethoxylation reaction promoted by palladium(0), while further hydrolysis aflbrded the targeted acids after protonation. Corresponding europium complexes show interesting luminescence properties in water at biological pH values. Key words: bromination; carboalkoxylation; bipyridine-carboxylate; Eu complexes; luminescence. [ABSTRACT FROM AUTHOR] |
