2-CHLOROETHANESULFONYL CHLORIDE Usage And Synthesis

Chemical Properties

CLEAR SLIGHTLY YELLOW TO BROWN LIQUID

Uses

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.

General Description

A liquid. Density 1.56 g / cm3. Flash point exceeds 230°F.

Air & Water Reactions

Reacts with water to produce corrosive and toxic gaseous hydrogen chloride.

Reactivity Profile

2-CHLOROETHANESULFONYL CHLORIDE is incompatible with strong oxidizing agents, alcohols, amines, alkali. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
