实验过程

6.47 g (82.5 mmol) of acetyl chloride were added dropwise with stirring at 20° C. to a solution of 6.61 g (75.0 mmol) of neopentyl alcohol (2,2-dimethyl-1-propanol) and 6.76 g (82.5 mmol) of 1-methylimidazole. The reaction mixture was stirred for a further 30 min and then heated to 75° C. The suspension which had formed in the meantime was converted to a liquid biphasic mixture. Removal of the upper phase gave 8.40 g (theory: 9.76 g) of neopentyl acetate as a colorless oil having a purity of 98% (GC).
