报道了离子液体（8-乙基-1，8-二氮杂双环[5，4，0]-7-十一碳烯三氟甲磺酸盐和8-甲基-1，8-二氮杂双环[5，4，0]-7-十一碳烯三氟甲磺酸盐）作为一种安全可循环的反应介质，在碱存在下与醛通过Horner-Wadsworth-Emmons反应合成α-氟-α，β-不饱和酯。
The utility of ionic liquids (8-ethyl-1,8-diazabicyclo[5,4,0]-7-undecene trifluoromethanesulfonate and 8-methyl-1,8-diazabicyclo[5,4,0]-7-undecene trifluoromethanesulfonate) as a safe recyclable reaction medium for the synthesis of α-fluoro-α,β-unsaturated esters by the Horner–Wadsworth–Emmons reaction with aldehydes in the presence of base, is described.
