2,9-Disubstituted and 3,8-disubstituted 1,10-phenanthrolines have been converted to the respective 5,6-diamines in three steps. The new heterocycles have been employed in condensation reactions with a protected 1,2-dialkynyl-1,2-dione to afford solubility-improved, acetylenic pyrazinophenanthrolines (pyzphen). In an initial study, the synthetic scope of these novel acetylenic ligands is evaluated. Georg Thieme Verlag Stuttgart.
