Amine formylation via carbon dioxide recycling catalyzed by a simple and efficient heterogeneous palladium catalyst

摘要

A simple and efficient Pd/Al_2O_3-NR-RD catalyst was prepared by depositing palladium on a shape controllable Al_2O_3-NR support through a two-step process that involves hydrothermal synthesis of Al_2O_3-NRs followed by reductive-deposition of palladium. This catalyst showed high activity in the catalytic formylation of amines by CO_2-H_2 under mild conditions with up to 96% yield.
