Diaryliodonium salts with fluorines have potential bioactivity. Vicinal trifluoromethanesulfonate substituted diaryliodonium salts were synthesized for the purpose of studying their anti-bacterial properties aganist Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis). Firstly, their chemical structures were characterized by 1H NMR, 13C NMR, 19F NMR and mass spectra. The minimum inhibitory concentration (MIC) of these compounds was tested by the micro-broth dilution method. The most active 2-((3-fluorophenyl)(((trifluoromethyl)sulfonyl)oxy)-l3-iodanyl)- phenyl trifluoromethanesulfonate (1) containing fluorine group gave the promising results for Escherichia coli (E. coli), Staphylococcus aureus (S. aureus) and Bacillus subtilis (B. subtilis) (MIC values of 16, 4 and 4 μg·mL-1), which is significantly lower than the commercial antibacterial agent of isothiazolinones. Scanning electron microscope (SEM) analysis sugggested that the compound led to the death of bacteria. Cytotoxicity tests showed that the compound 1 as well as isothiazolinones had a slight effect on the growth of Hela cells in vitro conditions.
