A process for the preparation of fluoroformates of the formula
wherein R1 is a saturated or unsaturated, substituted or unsubstituted and primary or secondary aliphatic, a saturated or unsaturated, substituted or unsubstituted secondary cycloaliphatic or a substituted or unsubstituted aromatic or heteroaromatic, and n is equal to 1, 2 or 3, comprising reacting a corresponding chloroformate of formula I with an alkali metal fluoride in ethylene carbonate at a temperature wherein the ethylene carbonate is liquid whereby it is possible to very rapidly obtain the fluoroformates with excellent yields and high purity.
一种制备化学式为的氟甲酸酯的方法,其中R1是饱和或不饱和的、取代或未取代的一级或二级脂肪族、饱和或不饱和的、取代或未取代的二级环脂肪族或取代或未取代的芳香族或杂芳香族,n等于1、2或3,包括在乙烯碳酸盐中以液态状态下的温度反应式I的相应氯甲酸酯和碱金属氟化物,从而可以非常快速地获得优良的收率和高纯度的氟甲酸酯。
