Synthesis method of di-tert-butyl dicarbonate: Potassium tert-butoxide is dissolved in anhydrous tetrahydrofuran, and dried carbon dioxide is introduced at -5～-20℃ to form a slurry. Continue to keep the low temperature and add phosgene benzene solution dropwise to prepare Obtain di-tert-butyl tricarbonate. Dissolve it in carbon tetrachloride, add an appropriate amount of 1,4-diazabicyclo[2,2,2]octane, stir at 25°C to completely release the carbon dioxide and convert it into di-tert-butyl dicarbonate.
