Polyfluorination of aryl alkyl sulfides by IF5 with concomitant migration of the arylthio group.
[reaction: see text] In the reaction of p-chlorophenyl alkyl sulfides with IF(5), polyfluorination reaction took place on the alkyl chain with the migration of the arylthio group. Consequently, p-chlorophenyl polyfluoroalkyl sulfides, having 3-7 fluorine atoms depending on alkyl chain length, could be obtained selectively.
