Palladium nanocatalyst supported on dimethylamino‐functionalized syndiotactic polystyrene (Pd@ s PS‐NMe 2 ) showed high activity and selectivity for the N ‐monomethylation of various primary amines using methanol as methylation reagent under air. The excellent catalytic performance could be associated with the ultrafine palladium nanoparticles and high amine‐adsorbing capacity of the catalyst. The Pd@ s PS‐NMe 2 catalyst was highly robust, and could be easily recovered by filtration and reused more than ten times without decrease in activity and selectivity.
