N‐alkyl hydroxylamines are effective reagents for the amination of organoboronic acids in the presence of trichloroacetonitrile. This amination reaction proceeds rapidly at roomtemperature and in the absence of added metal or base, it tolerates a remarkable range of functional groups, and it can be used in the late‐stage assembly of two complex units.

dual-catalytic strategy for the radical decarboxylation functionalization of aliphatic carboxylic acids. The photoinduced ligand-to-iron charge transfer process under light was initially occurred to generate an unstabilized alkyl radical, and the copper catalyst delivered the radical and enabled the subsequent coupling reactions to form C–N or C–C bonds. By merging iron-catalyzed decarboxylation with copper catalysis
generation of alkylradicals from inert alkyl C-O bonds has been developed via an iron/borane reagent/alkoxide catalytic system, which can be employed for the synthesis of amines from nitroarenes with excellent efficiency. This reductive amination features good functional group compatibility and enables the late-stage amination of bio-relevant compounds, thus providing good opportunities for applications
