text: The molecule has two electrophilic sites, the carbon and the S(VI) center.
  CSI has been employed for the preparation of β-lactams, some of which are medicinally important. Thus, alkenes undergo a -cycloaddition to give the sulfonamide.  The SOCl group can be removed simply by hydrolysis, leaving the secondary amide.
  Other reactions of CSI:
  *Cycloaddition to alkynes to give 1,2,3-oxathiazine-2,2-dioxide-6-chlorides.
  *Conversion of primary alcohols to carbamates.
  *Conversion of carboxylic acids and the acid chlorides into nitriles.
  *Preparation of N,N-disubstituted sulfamides, RNSONH
  *Preparation of Burgess reagent
