One-pot amination of cyclohexanone-to-secondary amines over carbon-supported Pd: Unraveling the reaction mechanism and kinetics

Luis E. Arteaga-Perez et al.

Summary: The use of NaCO2H has little impact on reactivity but does affect the selectivity to secondary amines in the liquid phase amination of cyclohexanone and aniline. The limited effectiveness of H2 transfer, hydrogen solubility in toluene, and mass transfer from liquid to catalyst surface are key factors influencing selectivity. The experimental observations support a multi-step mechanism involving condensation of ketone and amine to form an imine, followed by disproportionation into secondary amines with the surface reaction to form the intermediary imine being the rate limiting step.
