Despite the economic and environmental merits of iron, organoiron species is largely underused for catalysis, mainly because of the difficulty in controlling its reactivity. In this account, I describe our efforts toward controlling the reactivity of transient organoiron species and its utilization for catalytic C-H bond activation. The design of an organoiron species stabilized by a bidentate directing group and a diphosphine ligand, its applications to the catalytic reaction of carboxamides with organometallic reagents or with electrophiles, and a recent iron catalyst stabilized by a triphosphine ligand capable of activating the C-H bond of weakly coordinating carbonyl compounds are described.
