Iron-catalyzed reduction of carboxylic and carbonic acid derivatives

•Iron-catalyzed reduction reactions of carbonic and carboxylic derivatives have been reviewed.•Reaction mechanisms and the role of metal complexes have been discussed.•Ligands are important in most of these catalytic systems.

This review presents recent advances in reduction of carboxylic and carbonic derivatives by means of iron catalysis. It reveals the strong efforts, which have been devoted to the discovery of new ligands and catalysts during the last decade.
