Aplicação
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]

Mechanical alloying is a “brute force” method of affecting alloying and chemical reactions. The mixture of reactant powders and several balls are placed in the milling jar of a high-energy ball mill, for example, a shaker mill or a planetary mill.
Higher transition metal silicides are ideal for anisotropic thermoelectric conversion due to their Seebeck coefficient anisotropy and mechanical properties.
