Abstract

Abstract This report describes a new palladium catalyzed synthesis of 4-cyano-1, 10- phenanthroline (nphen, 1), 4, 7-dicyano-1, 10-phenanthroline (dnphen, 2) and their corresponding ruthenium complexes. The two cationic complexes,[(tbbpy) 2 Ru (nphen)] 2+ 3 and [(tbbpy) 2 Ru (dnphen)] 2+ 4 (tbbpy= 4, 4′-di-tert-butyl-2, 2′-bipyridine), were synthesized using an improved microwave procedure. All compounds were fully ...
