A unique one-pot, high-yield desulfurative−fluorination−bromination reaction which leads to the synthesis of 2,5-dibromo-3-(1,1-difluoroalkyl)thiophenes is reported. A single dithiolane reactant can be used to produce both 2,5-dibromo-3-(1,1-difluoroalkyl)thiophene and 3-(1,1-difluoroalkyl)thiophene with longer alkyl chains.
据报道,一种独特的一锅高产率的脱硫-氟化-溴化反应可合成2,5-二溴-3-(1,1-二氟烷基)噻吩。单个二硫杂环戊烷反应物可用于生产具有更长烷基链的2,5-二溴-3-(1,1-二氟烷基)噻吩和3-(1,1-二氟烷基)噻吩。
