4-Oxo-7-Halosubstituted Phenanthroline Diamides Bifunctional Reactivity: A Synthetic Pathway to Unsymmetrical Polydentate Ligands

An efficient approach to unsymmetrical 1,10-phenanthroline-2,9-dicarboxamides based on the bifunctional reactivity of 4-oxo-7-haloderivatives is reported. These substrates exhibit orthogonal reactivity, enabling selective nucleophilic aromatic substitution at the C7 position alon...
