Reaction of alkylhydrazines. II. vic-disubstituted pyridines and pyridopyridazines

A series of 2,3-disubstituted pyridines and pyrido[2,3-d]pyridazines have been synthesized. The molecular structure of the compounds have been elucidated by using chromatography; ir, nmr, and mass spectrometry; and chemical methods, in particular metal complexation. The new compounds offer interesting chemistry and are envisaged to function as potential chemotherapeutic and pharmacodynamic agents.
