Abstract: The tetrafluoro-λ6-sulfanyl (SF4) moiety has been relatively undeveloped since its discovery in the 1970s. In this study, we synthesized pyridine-SF4-isoxazolines, in which the two heterocycles are connected by a rodlike trans-SF4 linker, via the regioselective… read more here.

Abstract: An addition reaction of pyridine-tetrafluoro-λ6-sulfanylchlorides (Py-SF4Cl) to alkynes and alkenes providing pyridine-tetrafluoro-λ6-sulfanyl-alkenes and pyridine-tetrafluoro-λ6-sulfanyl-alkanes is represented. The addition of Py-SF4Cl occurs spontaneously in the presence of reactants, even in total darkness, but is affected in… read more here.
