We have recently developed the Pd/C-catalyzed monoalkylation method of primary amines using nitriles as an alkylating agent under hydrogenation conditions (Sajiki et al. 2004). In general, N-alkylation of α-amino acids is performed using stoichiometric methods, such as reductive alkylation with aldehydes, which use inorganic reductants or

A selective and catalytic mono-N-alkylation method of both aromatic and aliphatic amines using nitriles as an alkylating agent with Pd/C or Rh/C as a catalyst is described. This method is

TiO2 loaded with Pd particles (Pd/TiO2), when photoirradiated at λ > 300 nm in alcohol containing primary amine, efficiently promotes N-monoalkylation of amine with alcohol, producing the

We have developed an environmentally benign protocol for N -monoalkylation of primary amines with alcohols using sulfated tungstate as heterogeneous catalyst. Elimination Platinum on carbon-catalysed site-selective H–D exchange reaction of allylic alcohols using alkyl amines as a hydrogen source Org. Chem. Front. 2022, 9, 1986–1991. Recent Literature Iridium complexes bearing an N -heterocyclic carbene (NHC) ligand exhibited high catalytic performance for the N -methylation of both aliphatic and aromatic primary amines

Selective N-monoalkylation of aromatic amines with 1° and 2° alcohols and conversion of aromatic amines to amides are performed immediately and in excellent yields

N -Monoalkylation of primary amines is attained with a 1:1 aldehyde to amine ratio, whereas excess of the aldehyde (≥2:1) allows second alkylation, giving rise to tertiary A new one-pot method has been developed for the selective synthesis of secondary amines via reductive amination of the corresponding nitriles using Pt nanowires as a catalyst. A selective and catalytic mono-N-alkylation method of both aromatic and aliphatic amines using nitriles as an alkylating agent with Pd/C or Rh/C as a catalyst is described. This method is

Abstract Nitriles were found to be highly effective alkylating reagents for the selective N-alkylation of amines under catalytic hydrogenation conditions. For the aromatic primary amines, the The use of aqueous ammonia is essential for a palladium-catalyzed allylic amination for the preparation of primary amines. It is noteworthy that ammonia gas did not react at all. The first

The studies mainly focused on the N-alkylation of aromatic and primary amines [13], [14], [15], and the imine hydrogenation was proposed as the rate-determining reaction As a special highlight, we report the chemoselective monomethylation of primary amines using methanol under mild conditions.
