Visible-light driven reaction of CO₂ with alcohols using a Ag/CeO₂ nanocomposite: first photochemical synthesis of linear carbonates under mild conditions

Abstract

The first photochemical synthesis of linear carbonates from the reaction of CO2 with alcohols using silver-doped ceria nanocomposite at room temperature under visible light irradiation is described. DFT calculations suggested...

Cyclic Carbonates through the Photo-Induced Carboxylative Cyclization of Allylic Alcohol with CO2: A Comprehensive Kinetic Study of the Reaction Mechanism by In Situ ATR-IR Spectroscopy

“…In addition, the proposed mechanism was supported by a few mechanistic experiments conducted mostly using 1 H NMR. Very recently, Jain et al reported the first photochemical synthesis of linear carbonates from the reaction of CO 2 with alcohols using a silver-doped ceria nanocomposite at room temperature under visible light irradiation [48]. In this context, we decided to investigate the synthesis of cyclic carbonates through a onepot multicomponent metal-free process which merges the photo-promoted Atom Transfer Radical Addition (ATRA) of a perfluoroalkyl iodide (Rf-I) onto unsaturated alcohols with the Lewis-base-promoted carboxylative cyclization (Scheme 1).…”
