Provided is a preparation method for a fluorine-containing 1,3-dioxocycloalkane olefin, comprising: first, reacting a compound of formula (I) with a compound of formula (II) to obtain a compound of formula (III); and then further reacting the compound of formula (III) with an F source to obtain a compound of formula (IV), and finally, first converting the compound of formula (IV) into a compound of formula (V), followed by the conversion of the compound of formula (V) into a 1,3-dioxacycloalkane olefin of formula (VI). The preparation method not only has a wide range of sources of raw materials, but also has a wide applicability and may be used for the preparation of fluorine-containing heterocyclic olefins, and has simple preparation processes, a good yield and is suitable for industrial production. |
