The invention discloses a 3, 3-difluoro-1, 5-hexadiene compound as well as a preparation method and an application thereof. The preparation method comprises the following steps: in an
inert gas
atmosphere, sequentially adding alpha-
trifluoromethyl styrene, allyltrimethylsilane,
tetrabutylammonium fluoride and a
solvent into a
reaction tube, and magnetically stirring uniformly to obtain a mixture; performing a magnetic stirring reaction on the mixture for 12 h under the condition of a 130 DEG C
oil bath, cooling the reaction mixture to the
room temperature, and obtaining the 3, 3-difluoro-1, 5-hexadiene compound from the reaction mixture through rapid
column chromatography separation. The compound can be used for synthesizing a precursor compound containing a CF2 organic framework. The preparation method has the advantages of
high selectivity, economy,
environmental protection, simple operation, cheap and easily available raw materials, and is suitable for industrial application.
