General description

N-Chlorophthalimide in anhydrous acetic acid serves as a useful oxidizing reagent for use in various direct titrimetric analyses. N-Chlorophthalimide can be synthesized by reacting phthalimide, t-butyl hypochlorite, water and t-butyl alcohol. It participates in the synthesis of 2-amino-3-benzoyl-α-(methylthio)phenylacetamide.

Application

N-Chlorophthalimide may be employed in the synthesis of:
  • α-amino acetal
  • α-amino nitro compounds
  • vicinal diamine
  • α,β-unsaturated vicinal haloamino nitro compound
It may also be used as a chlorination reagent for the synthesis of 3-(methylthio)oxindoles.
