Starting from 5,6-dioxo-1,10-phenanthroline-2,9-dicarboxylic acid, the first examples of unsymmetrical 1,10-phenanthroline-2,9-diamides were obtained, simultaneously containing in their structure an oxo group in position 6 and a dichloromethylene fragment in position 5. The structure of the obtained compounds was confirmed by NMR spectroscopy and X-ray structural analysis.
