Pincer‐Type Complexes for Catalytic (De)Hydrogenation and Transfer (De)Hydrogenation Reactions: Recent Progress

Pincer complexes are becoming increasingly important for organometallic chemistry and organic synthesis. Since numerous applications for such catalysts have been developed in recent decades, this Minireview covers progress in their use as catalysts for (de)hydrogenation and transfer (de)hydrogenation reactions during the last four years. Aside from noble‐metal‐based pincer complexes, the corresponding base metal complexes are also highlighted and their applications summarized. Pincers of power: This minireview is focused on the recent progress of the application of various precious and non‐precious metal pincer‐type catalysts. Besides hydrogenation reactions, their utilization for dehydrogenation and transfer (de)hydrogenation reactions is also described. Especially, but not exclusively, the usage of ruthenium and iron pincer complexes is highlighted for CC, CN, and CO bond transformations.
