A polyhedral oligomeric silsesquioxane-based catalyst for the efficient synthesis of cyclic carbonates

A polyhedral oligomeric silsesquioxane-based catalyst for the efficient synthesis of cyclic... Polyhedral oligomeric silsesquioxane functionalized with imidazolium chloride peripheries ( POSS-Imi ) was successfully synthesized through a novel synthesis protocol. The solid was extensively characterized via 1 H NMR, 13 C NMR and IR spectroscopy as well as combustion chemical analysis, mass spectrometry and transmission electron microscopy. Moreover, an in-depth investigation through 29 Si NMR was performed. POSS-Imi was used for the first time as a catalyst for the conversion of CO 2 and epoxides into cyclic carbonates with excellent results in terms of both yield and selectivity. The catalyst displayed improved catalytic performance with respect to unsupported 1-butyl-3-methylimidazolium chloride. The enhanced activity was ascribed to the proximity effect generated by the increased local concentration of imidazolium species surrounding the inorganic silsesquioxane core. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Catalysis Science & Technology Royal Society of Chemistry

Abstract

Polyhedral oligomeric silsesquioxane functionalized with imidazolium chloride peripheries ( POSS-Imi ) was successfully synthesized through a novel synthesis protocol. The solid was extensively characterized via 1 H NMR, 13 C NMR and IR spectroscopy as well as combustion chemical analysis, mass spectrometry and transmission electron microscopy. Moreover, an in-depth investigation through 29 Si NMR was performed. POSS-Imi was used for the first time as a catalyst for the conversion of CO 2 and epoxides into cyclic carbonates with excellent results in terms of both yield and selectivity. The catalyst displayed improved catalytic performance with respect to unsupported 1-butyl-3-methylimidazolium chloride. The enhanced activity was ascribed to the proximity effect generated by the increased local concentration of imidazolium species surrounding the inorganic silsesquioxane core.
