Abstract

New tetrapyridylethanes can be prepared as new tetradentate pyridine ligands via the aminolysis reaction of pyrylium dications, using an original oxidation process of phenylpyridyl methylenepyrans. Crystal structure analysis, and spectroscopic and electrochemical studies show the possibility for using these new ligands in coordination chemistry.
