| Abstract
| - A set of ligands bearing 6-bromo-2,2‘-bipyridinependant arms attached in the 5‘-position are described.Transformation of the bromo to an ester was performed bya carboethoxylation reaction promoted by low-valent Pd(0),while saponification followed by acidification gave the acids.The introduction of an appended function 3-nitrobenzyl,benzamidomethyl, and tert-butylacetyl opens the way tofurther functionalize these scaffolds for potential labelingof biological material. The synthetic protocols represent avaluable approach to the rational design of ligands bearingoxophilic and anionic sidearms.
