Versatile routes for synthesis of diarylamines through acceptorless dehydrogenative aromatization catalysis over supported gold–palladium bimetallic nanoparticles
palladium nanoparticle catalyst (Pd/TiO2) gave the desired diarylamines, the catalyticactivity was inferior to that of Au–Pd/TiO2. Moreover, the activity of Au–Pd/TiO2 was superior to that of a physical mixture of Au/TiO2 and Pd/TiO2. The present Au–Pd/TiO2-catalyzed transformation of cyclohexylamines proceeds through complex pathways comprising amine dehydrogenation, imine disproportionation, and condensation

The equilibration of the cis and trans isomers of four epimeric pairs of 3,4-dialkyl cyclohexanones (alkyl = Me, Et) have been studied quantitatively at different temperatures. The thermodynamic constants ΔH and Δs exhibit considerable variations depending on the nature (Me or Et) of the substituents. These quantities were also calculated from statistical considerations. Theoretical and experimental
