4-Ethenylbenzenesulfonyl fluoride

Description:

4-Ethenylbenzenesulfonyl fluoride, also known by its CAS number 705-33-9, is an organic compound characterized by the presence of both a vinyl group and a sulfonyl fluoride functional group. This compound features a sulfonyl group (-SO2-) attached to a benzene ring, which is further substituted with a vinyl group (-CH=CH2) at the para position. It is typically a colorless to pale yellow liquid with a pungent odor. The sulfonyl fluoride moiety makes it a reactive electrophile, which can participate in various chemical reactions, including nucleophilic substitutions. This compound is often used in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl-containing compounds. Due to its reactivity, it should be handled with care, as it can be corrosive and may pose health hazards upon exposure. Proper safety measures, including the use of personal protective equipment, are essential when working with this substance in a laboratory setting.
