The synthesis of dialkyl carbonates, versatile compounds with applications in organic synthesis, pharmaceuticals, and polymers, has attracted considerable attention due to their environmentally benign nature. Here, we describe the selective bimolecular nucleophilic substitution (SN2) reaction between primary secondary alkyl iodides 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)-based carbon dioxide-binding liquids. We show that TBD is a great candidate for bulk dioxide alcohol binding at 100°C. TBD-based carbonate salts are SN2 processes, allowing them work highly reactive iodide while eliminating unwanted base quaternization either acetonitrile or both 21°C 65°C. high reactivity these liquids toward backside processes low temperature explained by presence TBD.H+ guanidinium, revealing unique metal-free cation-assisted ion-pair process.

Ionic liquids (ILs) and deep eutectic solvents (DESs) have tremendous potential for reactive capture of CO 2 , due to their highly properties, including a wide electrochemical stability window, low volatility, high solubility.
