Bond Formation with Maintenance of Twofold Charge: Generation of C₂O₃²⁺ in the Reaction of CO₂²⁺ with CO₂

Abstract

100 years after the prediction of the existence of C2O3 by Berthelot, doubly charged C2O32+ has been identified as a product in the reaction of CO22+ with CO2 (see scheme). The occurrence of this reaction for such a small dication indicates that bond-forming processes might play a much larger role in reactions of dications than has been anticipated to date.
