Abstract

Novel processes for preparing arylsulfur pentafluorides are disclosed. Processes include reacting at least one aryl sulfur compound with a halogen and a fluoro salt to form an arylsulfur halotetrafluoride. The arylsulfur halotetrafluoride is reacted with a fluoride source to form a target arylsulfur pentafluoride.

2. An arylsulfur chlorotetrafluoride is selected from the group consisting of 4-(tert-butyl)phenylsulfur chlorotetrafluoride, 4-fluorophenylsulfur chlorotetrafluoride, 2-fluorophenylsulfur chlorotetrafluoride, 4-chlorophenylsulfur chlorotetrafluoride, 4-bromophenylsulfur chlorotetrafluoride, 3-bromophenylsulfur chlorotetrafluoride, 2,6-difluorophenylsulfur chlorotetrafluoride, 2,4,6-trifluorophenylsulfur chlorotetrafluoride, and 2,3,4,5,6-pentafluorophenylsulfur chlorotetrafluoride.
