A process for preparing a poly(halotetrafluorosulfanyl)aromatic compound having a formula: the process comprising: reacting an aryl sulfur compound having a formula: with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens, and a fluoro salt having a formula, to form the poly(halotetrafluorosulfanyl)aromatic compound, M + F - in which: one or two of R 1", R 2", R 3", R 4", and R 5" are a SF 4 X group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; one or two of R 1', R 2', R 3', R 4', and R 5' are a SR 6 group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; R 6 is a hydrogen atom, a silyl group, a metal atom, an ammonium moiety, a phosphonium moiety, or a halogen atom; or R 6 combines with another R 6 of its own molecule or another molecule to form a single bond; M is a metal atom, an ammonium moiety, or a phosphonium moiety; and X is a chlorine atom, a bromine atom, or an iodine atom; or reacting an arylsulfur trifluoride having a formula; with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens, and a fluoro salt having a formula, to form the poly(halotetrafluorosulfanyl)aromatic compound: M + F - in which: one or two of R 1", R 2", R 3", R 4", and R 5" are a SF 4 X group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; one or two of R 1"', R 2"', R 3"', R 4"', and R 5"' are a SF 3 group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; M is a metal atom, an ammonium moiety, or a phosphonium moiety; and X is a chlorine atom, a bromine atom, or an iodine atom. reacting an aryl sulfur compound having a formula: with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens, and a fluoro salt having a formula, to form the poly(halotetrafluorosulfanyl)aromatic compound, M + F - in which: one or two of R 1", R 2", R 3", R 4", and R 5" are a SF 4 X group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; one or two of R 1', R 2', R 3', R 4', and R 5' are a SR 6 group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; R 6 is a hydrogen atom, a silyl group, a metal atom, an ammonium moiety, a phosphonium moiety, or a halogen atom; or R 6 combines with another R 6 of its own molecule or another molecule to form a single bond; M is a metal atom, an ammonium moiety, or a phosphonium moiety; and X is a chlorine atom, a bromine atom, or an iodine atom; or reacting an arylsulfur trifluoride having a formula; with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens, and a fluoro salt having a formula, to form the poly(halotetrafluorosulfanyl)aromatic compound: M + F - in which: one or two of R 1", R 2", R 3", R 4", and R 5" are a SF 4 X group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; one or two of R 1"', R 2"', R 3"', R 4"', and R 5"' are a SF 3 group and each of the remainders is selected from a group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 18 carbon atoms, a nitro group, and a cyano group; M is a metal atom, an ammonium moiety, or a phosphonium moiety; and X is a chlorine atom, a bromine atom, or an iodine atom.
