外文摘要：Metal- and solvent-free carboxylative cyclization of atmospheric CO2 with alkynol can be achieved using a 1-methylhydantoin anion-functionalized ionic liquid. 1H NMR, in situ FT-IR and DFT calculations indicate that the 1-methylhydantoin anion acts as a "pincer ligand" to form chelative interactions with the hydroxyl group, thereby effectively activating the alkynol.
