In the presence of a tert-butoxy radical precursor, the reaction of alkylamines with aryl halides was found to give alpha-arylated alkylamines through homolytic aromaticsubstitution of the halogen atoms.

primary, secondary, and tertiary aliphatic amines to give substitution products in which one of the cyano groups was replaced by the amine at α-CH position or by an alkyl group of the amine. o-Dicyanobenzene reacted similarly, but the meta-isomer did not react under similar conditions. The rates of the fluorescence quenching of p-dicyanobenzene with the amines are close to the diffusioncontrolled rate
dicyanodurene in acetonitrile in the presence of triethylamine gave mainly substitution and reduction products respectively, whereas a photochemical reaction of 1,2,4,5-tetracyanobenzene in the presence of N-methylpyrrolidine or nicotine gave tricyanoaniline, an amination product, as well as substitution products.

A metal-free convergent paired electrolysis strategy to synthesize benzylic amines through direct arylation of tertiary amines and benzonitrile derivatives at room temperature has been developed. This TEMPO-mediated electrocatalytic reaction makes full use of both anodic oxidation and cathodic reduction without metals or stoichiometric oxidants, thus showing great potential and advantages for practical

Here, we report a unique electrosynthetic method that enables the selective one-electron oxidation of tertiaryamines to generate α-amino radical intermediates over two-electron oxidation to iminium cations, providing easy access to arylation products by simply applying an optimal alternating current (AC) frequency. More importantly, we have discovered an electrochemical descriptor from cyclic voltammetry
