Abstract
Abstract A highly efficient carboxylative cyclization of propargylic alcohols with CO 2 under atmospheric pressure catalyzed by silver (0) nanoparticles decorated reduced graphene oxide (Ag‐rGO) is reported. Ag‐rGO was fully characterized by scanning electron microscope spectra (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT‐IR) spectra, Raman spectra and X‐ray photoelectron spectroscopy (XPS). Notably, Ag‐rGO can be also applied to the construction of other value‐added chemicals (β‐oxopropylcarbamates and 2‐oxazolidinones) from CO 2 at ambient conditions. In addition, Ag‐rGO is stable and reusable, which shows the potential for the practical application for CO 2 capture and utilization (CCU).
