Beschreibung

Anwendung

Iron powder is commonly used as the catalyst for a wide variety of organic transformations. Applications include:

• Reduction of nitroaromatic compounds to aromatic amines.
• 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).
• Synthesis of pyrrolo[1,2-a]quinoxaline derivatives.
• Conversion of ketoximes to the corresponding ketones by treatment with iron powder.
• Iron-catalyzed cross-coupling reaction of imidazoles with vinyl bromides and vinyl chlorides.
