Homogeneous catalysis using iron complexes: recent developments in selective reductions.

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 to other transition metals. Herein, we highlight promising attempts obtained in hydrogenation, transfer hydrogenation and hydrosilylation, which nicely illustrate the potential of iron and hopefully initialize a ferric future for catalysis. © The Royal Society of Chemistry 2011
