The reaction of nitro and amino fluorobromobenzenes of the type o-XCgF4Br and p-XCgF4Br where X = NOj or NHa with the pentafluoro benzenethiolate anion, in its copper(i) salt, resulted in the replacement of the bromine . The pentafluorobenzenethiolate anion or the anion of 2,3,5,6-tetrafluoro-4-mercaptopyridine, replaced the fluorine ortho or para to the nitro group in nitropentafluorobenzene. Para substitution only occurred in solvents of high dielectric constant, such as DMF and acetonitrile, whereas in solvents of low dielectric constant, such as ether, mixed replacement of ortho- and para-fluorine was observed . Increasing ionization of the thiol is postulated to cause predominantly para substitution.
