Patent ID: 7592491

Claim:
A process for preparing an arylsulfur pentafluoride having a formula (I) as follows: the process comprising: reacting at least one aryl sulfur compound having a formula (IIa) or a formula (IIb): with a halogen selected from the group consisting of chlorine, bromine, iodine, and interhalogens and a fluoro salt having a formula (III) to form an arylsulfur halotetrafluoride having a formula (IV): M + F − (III) and reacting the obtained arylsulfur halotetrafluoride with a fluoride source to form the arylsulfur pentafluoride; 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; R 6 is a hydrogen atom, a silyl group, a metal atom, an ammonium moiety, a phosphonium moiety, or a halogen atom; 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.
