Sustainable Metal Catalysis with Iron: From Rust to a Rising Star?

Among the shades! With respect to its availability, low toxicity, and price, iron should be one of the most used metals in homogeneous catalysis. Surprisingly, so far the application of iron is underdeveloped in comparison with other transition metals. Some promising attempts obtained in redox reactions and coupling chemistry which nicely illustrate the potential of iron and hopefully initialize a ferric future for catalysis are highlighted.
