Patent ID: 8653302

Claim:
A process for preparing a poly(pentafluorosulfanyl)aromatic compound having a formula (I) as follows: the process comprising: reacting an aryl sulfur compound having a formula (II): with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens, and a fluoro salt having a formula (III), to form a poly(halotetrafluorosulfanyl)aromatic compound having a formula (IV): M + F − (III) and reacting the obtained poly(halotetrafluorosulfanyl)aromatic compound with a fluoride source to form the poly(pentafluorosulfanyl)aromatic compound; in which: one or two of R 1 , R 2 , R 3 , R 4 , and R 5 are a SF 5 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; 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; 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.
