Wang, Chen-Gang published the artcileCarbon Dioxide Mediated Cellulose Dissolution and Derivatization to Cellulose Carbonates in a Low-pressure System, Synthetic Route of 939-99-1, the publication is Carbohydrate Polymer Technologies and Applications (2022), 100186, database is CAplus.

An effective switchable solvent system using carbon dioxide (CO₂) and 2-tert-butyl-1,1,3,3-tetramethylguanidine (BTMG) for cellulose dissolution and derivatization was developed. High concentration cellulose solution (up to 10 wt%) could be achieved by dissolving microcrystalline cellulose rapidly, within 5 min, into DMSO in presence of BTMG and 1 atm CO₂ at room temperature The cellulose-carbonate anion intermediate was characterized by ¹H and ¹³C NMR spectroscopies, emphasizing the generation of cellulose carbonate anions and protonated BTMG. Addition of organochlorides into the cellulose solution triggers a nucleophilic substitution with cellulose-carbonate anions, producing various cellulose benzyl carbonates and a cellulose-carbonate-ester with degree of substitution (DS) up to 1.83 at 1 atm CO₂ pressure and room temperature The activation energy (Ea) and Gibbs free energy change (ΔG) of CO₂-mediated dissolution and nucleophilic substitution were calculated by d. functional theory. The results showed that the nucleophilic substitution is the rate-limiting step.
