WE CLAIM :
Claim 1
A method for preparing an arylsulfur pentafluoride having a fonnula (I) as follows: the process comprising: reacting an arylsulfur halotetrafluoride having a formula (II): with hydrogen fluoride in the presence of an organic Compound to form the arylsulfur pentafluoride, in which the organic Compound has one or more unsaturated bonds in a molecule; in which: R1, R2, R\ 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; and X is a chlorine atom, bromine atom, or iodine atom. [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 organic Compound is in the ränge of about 1:0.05 to about 1:5.
