General description

Chloramine-T trihydrate is a widely used oxidizing agent in organic synthesis. It acts as a source of halonium cation and nitrogen anion and thus acts as a base and nucleophile. Due to its reactivity with a wide range of functional groups, it is involved in different molecular transformations. It is effective in acidic, neutral, and basic conditions[1].

Application

Chloramine-T trihydrate can be used as:
  • A reagent for chlorination in drinking water treatment[1].
  • A dehydrogenating agent for the oxidative dehydrogenation of aromatic aldehyde phenylhydrazones to synthesize nitrile imines[2].
  • The nitrene source for the aziridination of alkenes and the amidation of cyclic ethers[3].
