Halogenated S-(perfluoroalkyl)dibenzothiophenium salt represented by the following general formula (I):
This compound is a new, reactive, and industrially useful reagent for perfluoroalkylating organic compounds. The reagent can be prepared by a one-pot process or a two-step reaction process from a halogenated biphenyl and easily isolated by a filtration method. In addition, the halogenated biphenyl can be recovered by desulfurization from a halogenated dibenzothiophene obtained as a side-product by the usage of the reagent.
由以下通式 (I) 代表的卤代 S-(全氟烷基)二苯并噻吩盐:
该化合物是一种新型、活性和工业上有用的全氟烷基化有机化合物试剂。该试剂可通过一锅法或两步反应法从卤化联苯中制备,并可通过过滤法轻松分离。此外,卤化联苯还可以通过脱硫从使用该试剂得到的副产品卤化二苯并噻吩中回收。
