Difluoroketene thioacetal (2) prepared from trifluoroacetaldehyde thioacetal (3) with lithium diisopropylamide or alkyllithiums has been shown to be useful as a building block for the preparation of α-monofluoroalkanoic acids (5), which involves the reaction of 2 with various organometallic compounds followed by hydrolysis of the resulting monofluoroketene thioacetal (4).
由三氟乙醛硫缩醛 (3) 与二异丙基氨基锂或烷基锂制备的二氟乙烯酮硫缩醛 (2) 已被证明可用作制备 α-单氟链烷酸 (5) 的结构单元,其中涉及 2 与各种有机金属化合物的反应,然后通过水解生成的单氟乙烯酮硫缩醛 (4)。
