A one-pot procedure for the synthesis of 2-fluoro-3-trifluoromethyl- substituted thiophens 6 from 1-aryl-4,4-difluoro-3- trifluoromethylbut-3-en-1-one (3) and phosphorus pentasulfide is described. The fluorine atom at C-2 of compounds 6 undergoes nucleophilic displacement reactions.
描述了一锅法从1-芳基-4,4-二氟-3-三氟甲基丁-3-烯-1-酮(3)和五硫化二磷合成2-氟-3-三氟甲基取代的噻吩6的方法。化合物6的C-2处的氟原子经历亲核取代反应。
