have found limited use as catalysts. We demonstrate the TAPS-catalyzed carbondioxide fixation at atmosphericpressure for the coupling reaction with epoxides. Five-membered cyclic carbonates were obtained, including enantio-enriched carbonates. Mechanistic studies revealed the origin of the behavior of TAPS to be the in situ formation of an active species by TAPS addition to epoxides via halohydrin intermediates
