DMSO methylates a broad range of amines in the presence of formic acid, providing a novel, green and practical method for aminemethylation. The protocol also allows the one‐pot transformation of aromatic nitro compounds into dimethylated amines in the presence of a simple iron catalyst.
An aminated series: A well‐defined iron‐catalyzed reductive amination reaction of aldehydes and ketones with aliphatic amines using molecular hydrogen is presented. Under mild conditions, good yields for a broad range of alkyl ketones as well as aldehydes were achieved.

protocol for iodotrimethylsilane‐mediated deoxy‐functionalization of primary and secondaryalcohols was described. This protocol involves iodination of alcohol and then replaced by a N, S, or O nucleophile. Compared with traditional Mitsunobureaction, non‐acidic pre‐nucleophiles can be used in this protocol and configuration of alcohols can be retained.

frustrated Lewis pair” approach, a cyclopentadienone iron tricarbonyl complex has been designed and applied in the reductiveamination and hydrogenation of bicarbonate. This well‐defined phosphine‐free complex displays the best activities reported to date for an ironcomplex in the reduction of bicarbonate into formate and in reductiveamination.
Reductive amination under hydrogen pressure is a valuable process in organic chemistry to access amine derivatives from aldehydes or ketones. Knölker’s complex has been shown to be an efficient iron catalyst in this reaction. To determine the influence of the substituents on the cyclopentadienone ancillary ligand, a series of modified Knölker’s complexes was synthesised and fully characterised. These
