o-Quinodimethane interemediate was generated from o-[(trimethylsilyl)methyl]benzyl acetate with potassium fluoride. The o-quinodimethane in hand reacted with electron-deficient olefins, affording [4+2] cycloadducts, tetrahydronaphthalenes.
o-奎诺二甲烯中间体是通过
氟化
钾从o-[(三甲基
硅基)甲基]
苄酸乙酯生成的。得到的o-奎诺二甲烯与电子缺乏的烯烃反应,生成[4+2]环加成物,即四氢
萘类化合物。
