Bis[2-(perfluoroalkyl)ethyl]cyclopentadienes were synthesized from lithium [2-(perfluoroalkyl)ethyl]cyclopentadienides and 2-(perfluoroalkyl)ethyl triflates as mixtures of four regioisomers, structure of which was determined by 1H and 13C NMR spectroscopy. 2-(Perfluoroalkyl)ethyl triflates are useful fluorinated building blocks that can be employed in the synthesis of functionalised polyfluorinated
由[2-(全氟烷基)乙基]环戊二烯酸锂和2-(全氟烷基)乙基三氟甲磺酸酯作为四种区域异构体的混合物合成双[2-(全氟烷基)乙基]环戊二烯,其结构由1 H和13 C NMR光谱确定。2-(全氟烷基)乙基三氟甲磺酸酯是有用的氟化结构单元,可用于合成官能化的多氟化物质。
