Abstract
The reactivity of some derivatives of 1,10-phenanthroline, both free, and in the presence of some metal ions (RuII, FeII, CoIII and CoII) provides clear evidence for metal ion alteration of reaction profile in situations where more than one reaction is possible. The optical activity of the RuII complexes is discussed. The conversion, by hydroxide ion, of 1,10-phenanthroline-5,6-dione to 4,5-diazafluoren-9-one is shown to follow the expected benzilic acid pathway: the ultimate formation of the ketone is rationalised in terms of its exceptional stability, also evident in the behaviour of the ligands in the mass spectrometer.Keywords
