IF5–pyridine–HFAir- and moisture-stable solidFluorination reagentDesulfurizing–fluorinationIF5–pyridine–HF, an air- and moisture-stable solid, can be used as a fluorination reagent for theintroduction of fluorine atoms to the α-position of the sulfur atom in sulfides. The desulfurizing–...
Stable fluorinating reagent, IF5-pyridine-HF, was used for the polyfluorination of aryl alkyl sulfides. The introduction of three fluorine atoms with a concomitant migration of the arylsulfanyl group was achieved. Carrying out the reaction at 80 degrees C and presence of a methyl substituent on...
The title reagent, prepared by mixing equimolar amounts of IF5 with HF· pyridine, is found to be an efficient reagent for the desulfurative fluorination of thio compounds as well as introduction of fluorine to the -position of sulfides.doi:10.1002/chin.201315034...

When a dithiocarbonate (9) was reacted with IF5-pyridine- HF, the corresponding (methylsulfanyl)difluoromethyl ether (10) was selectively formed. On the other hand, when the reaction was carried out in the presence of Et3N-6HF, the corresponding trifluoromethyl ether (11) was selectively ...
IF5-pyridine-HFThe iodofluorination of alkynes was carried out using IF5-pyridine-HF and hydroquinone. The iodofluorination of an internal alkyne and a terminal alkyne proceeded stereoselectively to give the corresponding iodofluoroalkenes. An unsymmetrically substituted internal alkyne and electron ...

IF5–pyridine–HF, an air- and moisture-stable fluorinating reagent, was applied to the synthesis of glycosyl fluorides from (phenylthio)glycosides. Common protecting groups of alcohol and diol can tolerate the reaction conditions performed, and therefore, the present method is applicable to the ...
