Reaktionsschritte
One mol of hexafluoroacetone was added dropwise at 0° C. to 1.1 mol of allylbromide in THF solution. The reaction was carried out at room temperature for 4 hours. After treating with HCl, the reaction mixture was extracted with H2O and ether, and the organic layer was evaporated under reduced pressure to provide an intermediate product, allylhexafluoroisopropanol. Cyclopentadiene (1 mol) and 1 mol of the intermediate product then were placed into a reactor and reacted at about 80° C. for about 24 hours.
