Synthesis is reported of five pyridine-containing bidentate ligands bearing nucleophilic groups at different positions. Their efficient solid- phase alkylation was demonstrated in the synthesis of a small library. These ligands are attractive building blocks for the construction of libraries of metal-binding compounds for various purposes.
