Reusable Amine-Based Structural Motifs for Green House Gas (CO2) Fixation

A series of compounds with an amine based structural motif (ASM) have been synthesized for efficient atmospheric CO2 fixation. The H-bonded ASM bicarbonate complexes were formed with an in situ generated HCO3- ion. The complexes have been characterized by IR, C-13 NMR, and X-ray single-crystal structural analysis. ASM bicarbonate salts have been converted to pure ASMs in quantitative yield under mild conditions for recycling processes.
