As aryl triflates are widely used in organic synthesis and medicinal chemistry, significant efforts have been directed towards the development of efficient methods for their synthesis. It was found that trifluoromethanesulfonyl pyridinium salt (C5H5N+SO2CF3·CF3SO-3) was able to act as a mild trifluoromethanesulfonylation reagent to convert phenols into aryl triflates. All aryl triflate products could be purified simply by washing, and tedious chromatography operations were avoided. Besides aryl triflates, vinyl triflates could also be synthesized by using this pyridinium salt as reagent. The pyridinium salt could be easily prepared and purified, is stable under dry atmosphere, and thus may become an easy-to-handle reagent.

Key words: aryl triflates, trifluoromethanesulfonylation, phenols, trifluoromethanesulfonyl pyridinium salt, fluorine
