Iron catalysis involves the use of iron-based compounds to accelerate chemical reactions without being consumed in the process. This method is significant in various industrial applications, including the production of chemicals and fuels. Iron is abundant, cost-effective, and environmentally friendly compared to other metals like platinum or palladium. In many reactions, iron catalysts can facilitate the transformation of simple molecules into more complex structures. They are particularly useful in organic synthesis and green chemistry, where the goal is to minimize waste and energy consumption. The development of efficient iron catalysts continues to be an area of active research.
