Industrial methods for producing arylsulfur pentafluorides

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 additives to form the arylsulfur pentafluoride, in which at least two additives are selected from a group consisting of fluoride salts of formula, M +− F(HF) n , non-fluoride salts of formula, M + Y − , and organic compounds that have one or more unsaturated bonds in a molecule;

in which: R 1 , R 2 , R 3 , R 4 , and R 5 each is independently a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a nitro group, a cyano group, a substituted or unsubstituted alkanesulfonyl group having 1 to 18 carbon atoms, a substituted or unsubstituted arenesulfonyl group having 6 to 30 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 18 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 30 carbon atoms, a substituted or unsubstituted acyloxy group having from 1 to 18 carbon atoms, a substituted or unsubstituted alkanesulfonyloxy group having from 1 to 18 carbon atoms, a substituted or unsubstituted arenesulfonyloxy group having from 6 to 30 carbon atoms, a substituted or unsubstituted alkoxycarbonyl group having 2 to 18 carbon atoms, a substituted or unsubstituted aryloxycarbonyl group having 7 to 30 carbon atoms, a substituted carbamoyl group having 2 to 18 carbon atoms, a substituted amino group having 1 to 18 carbon atoms, or a SF 5 group;

X is a chlorine atom, bromine atom, or iodine atom;

M is a metal atom, an ammonium moiety, or a phosphonium moiety;

n is 0 or a mixed number greater than 0; and

Y is an anion moiety whose conjugated acid, HY, is less than HX in acidity, and Y is not F(HF) n .

2. The method of claim 1 wherein the mol ratio of the arylsulfur halotetrafluoride to the total amount of the additives is in a range of about 1:0.1 to about 1:5.
