Compounds containing the pentafluorosulfanyl group (–SF5) possess high
electron-withdrawing property and strong lipophilic character. These compounds have been attracting attention as
potent building blocks in the fields of pharmaceuticals, agrochemicals and functional materials. For example, it
has been reported that compound a prepared from 3-bromophenylsulfur pentafluoride (1) is a SF5 analog of
fenfluramine, which is known as an anorectic agent, significantly enhances the affinity for the 5-HT2b,
5-HT2c and 5-HT6 receptors than fenfluramine.1)

In addition, it also has been reported that the liquid crystal using compound b, which is prepared
from 4-bromophenylsulfur pentafluoride (1), has significantly improved dielectric anisotropy
(Δε), compared with other fluorinated analogs such as –F and –CF3.2)
