Abstract:
The one-pot amination of natural terpene alcohol (myrtenol, with a primary hydroxyl group) was studied over gold catalysts supported on different metal oxides such as ZrO₂, MgO, Al₂O₃, CeO₂, La₂O₃ using the equimolar amounts of substrates under nitrogen pressure. The synthesized catalysts were characterized by TEM, N₂ adsorption techniques and XPS. The correlation between acid–base properties of support and catalytic performance was established. A nearly complete myrtenol conversion as well as the highest selectivity to secondary amine of about 52% were reached after 16 h over Au/ZrO₂ with both acidic and basic surface sites.
