Abstract
Novel processes for preparing arylsulfur pentafluorides are disclosed. Processes include reacting at least one aryl sulfur compound with a halogen and a fluoro salt to form an arylsulfur halotetrafluoride. The arylsulfur halotetrafluoride is reacted with a fluoride source to form a target arylsulfur pentafluoride.
Claims11
A process for preparing an arylsulfur pentafluoride having a formula (I):
- the process comprising:
- reacting an arylsulfur trifluoride having a formula (V):
- 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):
- and reacting the obtained arylsulfur halotetrafluoride with a fluoride source to form the arylsulfur pentafluoride;
- 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;
