The single fluorine atom of 2-fluoro-3-trifluoromethylfurans and -thiophenes can be readily replaced by various nucleophiles. Depending on the substituent pattern, certain products obtained upon nucleophilic substitution with benzyl alcohols are susceptible to [1,3]- and [1,5]-benzyl group migrations under very mild conditions. Therefore, these rearrangements can be integrated into domino reactions
2-氟-3-三氟甲基呋喃和-噻吩的单个氟原子可以很容易地被各种亲核试剂所取代。根据取代基的模式,在用苄醇进行亲核取代后获得的某些产物在非常温和的条件下易受[1,3]-和[1,5]-苄基迁移的影响。因此,这些重排可以整合到多米诺骨牌反应中。
