Novel methods for preparing arylsulfur pentafluorides are disclosed. Arylsulfur halotetrafluoride is reacted with a fluoride source under hydrous conditions to form an arylsulfur pentafluoride. The purification method is also disclosed.
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.

We report a stereoretentive cross-coupling reaction of configurationally stable nucleophiles with disulfide and N-sulfenylsuccinimide donors promoted by Cu(I). We demonstrate the utility of this method in the synthesis of thioglycosides derived from simple alkyl and aryl thiols, thioglycosides, and in the glycodiversification of cysteine residues in peptides. These reactions operate well with carbohydrate

direct allylic C(sp3)–H thiolation mediated by visiblelight photoredox catalysis. The use of in situ-generated thiylradical from disulfide as a hydrogen atom transfer (HAT) reagent and a coupling partner enabled selective cleavage of the allylic C(sp3)–H bond followed by C(sp3)–S bond formation. The undesired hydrothiolation, a prevalent reaction from facile thiylradical addition to olefins, was prevented
