Electronic Effect of Ruthenium Nanoparticles on Efficient Reductive Amination of Carbonyl Compounds
Highly selective synthesis of primary
amines over heterogeneous
catalysts is still a challenge for the chemical industry. Ruthenium
nanoparticles supported on Nb<sub>2</sub>O<sub>5</sub> act as a highly
selective and reusable heterogeneous catalyst for the low-temperature
reductive amination of various carbonyl compounds that contain reduction-sensitive
functional groups such as heterocycles and halogens with NH<sub>3</sub> and H<sub>2</sub> and prevent the formation of secondary amines
and undesired hydrogenated byproducts. The selective catalysis of
these materials is likely attributable to the weak electron-donating
capability of Ru particles on the Nb<sub>2</sub>O<sub>5</sub> surface.
The combination of this catalyst and homogeneous Ru systems was used
to synthesize 2,5-bis(aminomethyl)furan, a monomer for aramid production,
from 5-(hydroxymethyl)furfural without a complex mixture of imine
byproducts
