N-Heterocyclic and Mesoionic Carbenes of Manganese and Rhenium in Catalysis

The use of N-heterocyclic carbenes (NHCs) in manganese and rhenium catalysis is underdeveloped in comparison to other transition metals. Herein, we cover the recent and stimulating progress in homogeneous catalysis using Mn-NHC complexes, namely in hydrosilylation, hydrogenation, and borrowing hydrogen processes. Of particular interest is the application of Mn and Re NHC catalysts in the electrochemical and photochemical reduction of CO2.
