Synthetic method of fluoro-oxacyclic olefin

The invention discloses a synthesis method of fluoro-oxacyclic olefin. The method comprises the following steps of: performing selective fluorination reaction on chloro-oxacyclic alkane and a fluorination reagent to generate fluoro-chloro-oxacyclic alkane, and performing dehalogenation reaction on the fluoro-chloro-oxacyclic alkane under the action of a dehalogenation reagent to generate the target product fluoro-oxacyclic olefin. The method has the advantages of mild reaction conditions, high target product selectivity and the like.

Thermal Decomposition of Fluorinated Dioxolane Carboxylates

Synthesis of fluorodioxole olefin monomers by thermal decomposition of fluorinated dioxolane carboxylic acid and the corresponding acyl chloride was explored.Complex product formation is observed, including acyl fluoride from C1-F exchange, the hydro-dioxolane from proton abstraction, the cyclic ether ketone from dioxolane ring opening, and the epoxy acid fluoride from thermal rearrangement.The product distribution is strongly dependent upon reaction conditions.The main influential factors include the reaction temperature, the base used for the reaction, the presence or absence of solvent, and the counter ion associated with the intermediate salt.A mechanism is proposed to rationalize both the results and the product distribution.Methods to make authentic samples for product analysis are reported.
