Abstract: Fe(II)-phosphine complex [Fe(dpbz)]Cl2 was demonstrated to be effective for the intramolecular C(sp3)-H amination of organic azides. This catalyst exhibited a high catalytic capacity for the transformations from α-azido amides to imidazolinones. Cyclization of simple aliphatic… read more here.
