Applicazioni

Benzenesulfonyl chloride reacts with Grignard reagents to form oxindoles from N-unsubstituted indoles. It is widely used to check the assay of thiamine in different food products. It is involved in the synthesis of alpha-disulfones, sulfonamides and sulfoante esters as precursor. It is a derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry. It is common reagent used in Hinsberg test for detection and distinguishing the type of amines as primary, secondary and tertiary amines.

Note

Moisture sensitive. Incompatible with water, strong oxidizing agents, strong bases, methyl formamide and dimethyl sulfoxide.

Reacts with ß-hydroxy esters in pyridine to give ß-lactones which, at higher temperatures eliminate CO2 in a stereospecific alkene synthesis: J. Am. Chem. Soc., 94, 2000 (1972); J. Org. Chem., 39, 1322, 1650 (1974):

Alternatively, MgBr2 induces a ring-opening reaction leading to ß-unsaturated acids. See, e.g.: Synth. Commun., 19, 2243 (1989).
