Mesoporous zirconium phosphonates as efficient catalysts for chemical CO2 fixation†
Abstract
Mesoporous zirconium phosphonates were demonstrated as highly effective catalysts for the heterogeneously catalyzed cycloaddition reaction between aziridines and CO2 to yield oxazolidinones in a solvent-free system without introducing any co-catalysts or halogen species, exhibiting outstanding activity and selectivity, as well as excellent recyclability.
