Mechanochemical Activation of NaHCO3: A Solid CO2 Surrogate in Carboxylation Reactions
ChemSusChem, Volume 18, Issue 14, July 17, 2025.This study presents sodium bicarbonate (NaHCO3) as a safe, solid source of CO2 for mechanochemical carboxylation reactions. Mechanochemical methods for synthesizing cyclic carbamates and organic carbonates from NaHCO3 are developed. This approach holds significant potential for pharmaceutical applications, highlighting solvent‐minimized synthesis and ...
