Iron‐Catalyzed Intramolecular Aminations of C(sp3)−H Bonds in Alkylaryl Azides

Abstract The nucleophilic iron complex Bu 4 N[Fe(CO) 3 (NO)] (TBA[Fe]) catalyzes the direct intramolecular amination of unactivated C(sp 3 )−H bonds in alkylaryl azides, which results in the formation of substituted indoline and tetrahydroquinoline derivatives.
