Application

Iron powder is commonly used as the catalyst for a wide variety of organic transformations. Applications include:
  • Reduction of nitroaromatic compounds to aromatic amines.[1][2]
  • Iron-mediated polymerization of methyl methacrylate (MMA) in the presence of a reversible addition-fragmentation chain transfer (RAFT) agent, 2-cyanoprop-2-yl 1-dithionaphthalate (CPDN).[3]
  • Synthesis of pyrrolo[1,2-a]quinoxaline derivatives.[4]
  • Conversion of ketoximes to the corresponding ketones by treatment with iron powder.[5]
  • Iron-catalyzed cross-coupling reaction of imidazoles with vinyl bromides and vinyl chlorides.[6]
