This research representative developed various synthetic methodologies of polifunctionalized compounds by using interaction of iron catalyst and functionalized carbon-carbon multiple bonds. Specifically, the following items were carried out. 1) Application of iron-catalyzed selective addition to functionalized dienes of Grignard reagents. 2) Iron-catalyzed selective addition to sulfonyl dienes or functionalized enynes of Grignard reagents. 3) Application of iron-catalyzed selective substitution to functionalized diene monoepoxides of Grignard reagents. 4) Reductive homocoupling reaction of functionalized diene monoepoxides with iron catalyst-stereoselective synthesis of cyclopropanes. 5) Iron-catalyzed selective synthesis of peroxyacetals from benzyl ethers and tert-butyl hydroperoxide. 6) Iron-catalyzed preparation of amines from nitro compounds and Grignard reagents via reductive coupling reaction.
