The significance of this article is that a practical catalyst system for use in FeC 13-catalyzed intramolecular hydroamination where the iron-salt-catalyzed activity has been proven superior to the conventional transition-metal catalysts.Previously,high affinity of iron for olefins had not been applied in catalytic hydroamination and had only been done with reactions using cyclopentadienyliron dicarbonyl(FP)species and iron salts.
