Facile Synthesis of Tetrapyrido[2,3-a:3′,2′-c:2″,3″-h:3?,2?-j] phenazine
Bonh?te, Pierre,Wrighton, Mark S.
, p. 897 - 898 (1997)
The title compound, a potential ligand for transition metals, was prepared by coupling of two 4,7-phenanthroline-5,6-dione molecules in presence of ammonia under reductive conditions. A straightforward synthesis of 4,7-phenanthroline-5,6-dione is also presented.
