With suitable choice of conditions, mercuration of 4-methoxybenzoic acid in trifluoroacetic acid with added trifluoromethanesulphonic acid can give predominant 2, 5-dimercuration, 2, 3, 5-trimercuration, or formation of 2, 3, 4, 5-tetramercurated anisole in short reaction times, whereas use of trifluoroacetic acid alone gives 3-mercuration, 3, 5-dimercuration or, with long reaction times, 2, 3, 5-trimercuration.
