Iron and iron compounds are widely distributed in nature and can function as reagents or catalysts. For example, ferric chloride and bromide have long been used as Lewis acid iron catalysts in the classic electrophilic aromatic substitution reaction. Of particular interest are iron complexes with organic ligands, which can serve as environmentally friendly Fe catalysts for a host of transformations. Illustrating this point is the very useful role that iron catalysis is playing in the timely study of the ammonia-borane dehydrogenation process, since ammonia-borane (NH3:BH3, AB) is of interest as a hydrogen-storage material. Sigma-Aldrich offers a variety of iron catalysts and reagents. Search below to find the product that fits your research needs.
