Abstract
A process, composition, and apparatus for carbon dioxide (CO2) conversion are disclosed. The CO2 conversion comprises reacting CO2 with a cyclopropenimine (CPI) to activate the CO2 and transferring the activated CO2 to generate a product of the transferring. The transferring also generates a conjugate acid of the CPI. The process further comprises regenerating the CPI from the conjugate acid.
Claims8
