Synthese

24424-99-5

16466-61-8

General procedure for the synthesis of di-tert-butyl azodicarboxylate from di-tert-butyl dicarbonate: Hydrazine monohydrate (5.85 g, 85%, 200 mmol) was added dropwise to a methanol solution containing 50 ml of di-tert-butyl dicarbonate (48 g, 220 mmol) over a period of 30 min under ice bath cooling conditions. After the dropwise addition, the reaction mixture was stirred at room temperature for 3 hours. Subsequently, the methanol solvent was removed by rotary evaporator and 250 ml of n-hexane was added to the residue and the resulting white solid was collected by filtration and washed with n-hexane. A final white solid product of 19.34 g was obtained in 84% yield.
