The pentafluorosulfanyl (SF₅) group, as a unique fluorine-containing functional group, has demonstrated broad application prospects in medicinal chemistry, materials science, and other fields due to its excellent chemical stability, high electronegativity, and lipophilicity. In recent years, ...
Pentafluorosulfanyl chloride (SF₅Cl), a pivotal reagent for direct pentafluorosulfanylation, has seen remarkable advancements in synthesis and handling safety. Key developments include
In 2015, the Dolbier group reported a method where phenylacetylene is used as the substrate, reacting with SF₅Cl under the catalysis of triethylborane (BEt₃) to generate a chlorinated pentafluorosulfanylated intermediate (189).
