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: 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 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 SF5 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. |
