摘要: Approaches to control selectivity and activity in the catalytic reductive amination of butyraldehyde with ammonia over carbon supported noble metal catalysts (Ru, Rh, Pd, Pt) were explored. Detailed analysis reaction network shows that Schiff base N-[butylidene]butan-1-amine is most prominent initial product and, only after nearly all had been converted N-[butylidene]butan-1-amine, amines are detected mixture. From this intermediate, good hydrogenolysis Rh) produce mostly butylamine, while less active (Pd, lead hydrogenation dibutylamine.
