WE CLAIM:
[Claim 1]
A method for preparing an arylsulfur pentafluoride having a formula (I) as follows:
the process comprising:
reacting an arylsulfur halotetrafluoride having a formula (II):
with hydrogen fluoride in the presence of a non-fluoride salt of formula, M+Y~, to form the arylsulfur pentafluoride;
in which: R1, R2, R3, R4, and R5 each is independently a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, a cyano group;
X is a chlorine atom, bromine atom, or iodine atom;
M is a metal atom, an ammonium moiety, or a phosphonium moiety;
Y is an anion moiety derived from sulfate. carbonate. or carboxylic acid. whose conjugated acid, HY, is less than HX in acidity. [Claim 2]
The method of claim 1 wherein X is Cl. [Claim 3]
The method of claim 1 wherein the mol ratio of arylsulfur halotetrafluoride to non-fluoride salt is in a ränge of about 1:0.1 to about 1:5.

[Claim 4]
The method of claitn 1 wherein the mol ratio of arylsulfiir halotetrafluoride to hydrogen fluoride is in the ränge of about l:10toabout 1:150.
