以双环戊二烯为起始原料,经Diels-Alder反应、还原反应及酯化反应,合成得到双三氟甲磺酸亚降冰片烯-5基-二甲酯.选择毒性较低、易于得到的三氟甲磺酰氯做原料,去除有毒有害吡啶试剂的使用,保证无水无氧的环境,使得反应进行更彻底,得到的产物更纯净. Dicyclopentadiene as starting material, Diels-Alder reaction, reduction reaction and esterification reaction, bis-trifluoromethanesulfonic acid norbornene-5-yl-dimethyl ester was synthesized with low toxicity and easy to get Of trifluoromethanesulfonyl chloride as raw material to remove the use of toxic and harmful pyridine reagents to ensure that anhydrous oxygen-free environment, making the reaction more thoroughly, the resulting product more pure.
