The preparation was carried out as in Example 2 but using 120 g of ethylene carbonate, 45 g (0.77 mol) of potassium fluoride and 75.3 g (0.5 mol) of neopentyl chloroformate. After addition of the chloroformate, stirring of the reaction mixture was continued for 1 hour at 45° C. Evaporation under vacuum was carried out as in the preceding example. By distillation under reduced pressure, 61.7 g (92% yield) of neopentyl fluoroformate were recovered with a boiling point of 60° C. at 20 mm Hg.
