This invention relates to 2-pentafluarasulfanylnapthalene, substituted derivatives thereof and to a process for producing naphthalene carrying an SF5 group. A 3-step process is employed wherein 1,4-dihydronaphthalene is reacted with pentafluorosulfanyl halide. Next the resulting 3-halo-2-pentafluorosulfanylnaphthalene or derivative is converted to 2-pentafluorosulfanyl-1,4-dihydronaphthalene or derivative by treatment with a base and subsequently transformed into pentafluorosultanylnaphthalene by removing hydrogen atoms.
本发明涉及 2-五氟硫代萘及其取代衍生物,以及生产带有 SF5 基团的萘的工艺。本发明采用三步法,其中 1,4-二氢萘与五氟硫酰卤反应。接着,生成的 3-卤代-2-五氟硫酰基萘或衍生物通过碱处理转化为 2-五氟硫酰基-1,4-二氢萘或衍生物,然后通过去除氢原子转化为五氟硫酰基萘。
