研究了烯丙基 2-噻吩甲基醚的 Wittig 重排。烯丙基2-噻吩甲基醚(la-d)的去质子化优先发生在α-位或a'-位，具体取决于三种BuLi。噻吩甲醇和-乙醇衍生物分别作为[2,3]和[1,2]σ重排的产物获得。
Wittig rearrangement of allyl 2-thiophenemethyl ethers was studied. Deprotonation of allyl 2-thiophenemethyl ethers (la-d) occurred preferentially either the α- or the a'-position, depending on three kinds of BuLi. Thiophenemethanol and -ethanol derivatives were obtained as products of [2,3] and [1,2] sigmatropic rearrangements, respectively.
