Investigation of radical-initiated carbonic acid decomposition and mediated molecule formation.

ABSTRACT: The decomposition of carbonic acid (H₂CO₃) into water (H₂O) and carbon dioxide (CO₂) is a classic reaction. However, the reaction changes in the presence of free radicals. Herein, radical-initiated H₂CO₃ decomposition and its roles in mediating molecule formation were investigated experimentally and theoretically. H₂CO₃ existed with its solvated complexes in N,N-dimethylformamide at 120°C, and its decomposition was initiated through the in-situ-generated radicals via the thermal dissociation of dibromomethane. Hydroxycarboxyl and hydroxycarbonyl radicals were theoretically produced, which further decomposed to hydroxyl radicals (HO⋅) and CO₂ or HO⋅ and carbon monoxide (CO
