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

Abstract

A simple and efficient Pd/Al₂O₃-NR-RD catalyst was prepared by depositing palladium on a shape controllable Al₂O₃-NR support through a two-step process that involves hydrothermal synthesis of Al₂O₃-NRs followed by reductive-deposition of palladium. This catalyst showed high activity in the catalytic formylation of amines by CO₂–H₂ under mild conditions with up to 96% yield.
