2-Chloroethanesulfonyl chloride was used in one-pot sulfonylation/intramolecular thia-Michael protocol for the synthesis of 1,5,2-dithiazepine 1,1-dioxides. It was also used in synthesis of vinyl sulfonamides with a furan, carbocyclic, semi cyclic or acyclic 1,3-diene moiety.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

In the presence of a base, converts alcohols to vinyl sulfonates: J. Am. Chem. Soc., 68, 1797 (1946); Angew. Chem. Int. Ed., 4, 300 (1965). These electrophilic alkenes readily undergo conjugate addition reactions with various nucleophiles:
Reaction with pentafluorophenol, in the presence of Et3N, gives PFP vinylsulfonate, which can be converted to a sulfonamide via tin-mediated radical addition of alkyl halides to the olefinic bond, followed by displacement of the PFP group with an amine: Org. Lett., 42549 (2002).
