摘要:

一类含六个碳的长链叶立德通过分子内维蒂希反应可生成含氟多取代苯酚. 通过对中间产物及最终成环产物的1H NMR和13C NMR的分析,讨论了其化学位移及J-偶合特征. 同时研究了整个反应可能的历程和机理.

关键词: NMR, 多取代苯酚, 三苯膦, 三氟炔酯

Abstract:

A group of multi substituted phenols were prepared via intramolecular wittig reaction of a kind of long chain phosphonic ylides.The intermediate   and the  products were analyzed by 1H NMR and 13C NMR. Their chem ical shifts and J-coupling constants were studied. The reaction paths and m echanism were also proposed.

Key words: Multi substituted phenol, Triphenyl phosphine, Methyl perfluoroalkynoate
