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.
  • 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.

Articles

An article concerning self-propagating reactions induced by mechanical alloying, presented by Sigma-Aldrich.com.

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.

In recent years, the price of tellurium, a key component in the bestperforming thermoelectric materials, has increased significantly, leading to the question, “Is it economically viable to produce thermoelectric generators on an industrial scale?
