Synthesis method of 3-(pentafluorophenyl)propyl-trimethoxysilane

The invention relates to a synthesis method of 3-(pentafluorophenyl)propyl-trimethoxysilane, belonging to the technical field of battery electrolyte additives. According to the invention, pentafluorobenzene is used as a raw material for preparation of 3-(pentafluorophenyl)propyl-trimethoxysilane. The method comprises the following steps: A, under the protection of argon, adding THF and diisopropylamine into a reaction kettle, conducting stirring and cooling until a temperature T is less than or equal to -45 DEG C, dropwise adding n-butyllithium, performing heat preservation after dropwise addition of n-butyllithium, dropwise adding pentafluorobenzene, performing heat preservation after dropwise addition of pentafluorobenzene, dropwise adding 1,3-dibromopropane,performing heat preservation after dropwise addition of 1,3-dibromopropane, carrying out washing until a neutral product is obtained, separating liquid, conducting washing, separating liquid, and then successively performing drying, suction filtration and concentrating to obtain 1-(3-bromopropyl)pentafluorobenzene; and B, in an argon atmosphere, adding 1-(3-bromopropyl)pentafluorobenzene, trimethoxysilane and N,N-dimethylformamide into a reactor, stirring, adding organic alkali and tetrabutylammonium bromide, adding rhodium dicarbonyl acetylacetonate (I), heating a reaction mixture to 80-90 DEG C, conducting continuous stirring, carrying out standing, performing cooling to room temperature, and carrying out concentrating to obtain the 3-(pentafluorophenyl)propyl-trimethoxysilane. The product obtained by the synthesis method is relatively high in yield and high in purity.
