Palladium nano-particles as a recyclable catalyst for C–O bond formation under solvent free conditions†
The development of green, economical and sustainable chemical processes is one of the primary challenges in organic chemistry. Herein, we report a recoverable heterogeneous palladium catalyst for the stereoselective synthesis of multi-functionalized allylic ethers under solvent free conditions. This method is based on in situ generated PdNP catalyzed O-allylation of alcohols with vinyl cyclic carbonates. Solvent-free conditions, easily recoverable catalysts, efficient recycling, and operational simplicity make the protocol green, economic and sustainable.
