The present invention provides a process for preparing fluorinated 1,3-dioxolan-2-one by reacting a derivative of 1,3-dioxolan-2-one having halogen atom other than fluorine with an amine hydrofluoride in an organic solvent, and in this preparation process, fluorinated 1,3-dioxolane-2-on can be prepared in a short period of time by liquid-liquid reaction while maintaining high yield, by using a derivative of 1,3-dioxolan-2-one having halogen atom other than fluorine as a starting material and fluorinating the derivative with a fluorinating agent.
本发明提供了一种制备氟代1,3-二氧杂环己烷-2-酮的方法,该方法通过在有机溶剂中将含有氟以外卤素原子的1,3-二氧杂环己烷-2-酮衍生物与氨基氟化物反应,可在短时间内通过液-液反应制备氟代1,3-二氧杂环戊烷-2-酮,同时保持高收率,通过使用含有氟以外卤素原子的1,3-二氧杂环己烷-2-酮衍生物作为起始物质,并使用氟化试剂对衍生物进行氟化。
