White powder | [Uses]
DIH - Highly efficient and economical reagent for Iodination
Used for:
- Preparation of nitriles from corresponding alcohols and amines via oxidative conversion
- Chemoselective, stereospecific iododesilylation of silylated alkenes
- Preparation of N-benzyl toluenesulfonamides via sulfonylamidation of alkylbenzenes with toluenesulfonamide in presence of diiododimethylhydantoin
- Iodination reactions
| [Preparation]
1,3-diiodo-5,5-dimethylhydantoin is prepared by reaction of Iodine Monochloride (0.11 mol) with 5,5- dimethylhydantoin (0.05 mol) and Sodium Hydroxide (0.1 mol) in ice-water at 0 °C;1 the product is used without further purification. | [storage]
store under nitrogen at 0 °C and protect from light and moisture to avoid decomposition; irritating solid; avoid inhalation of the powder. |
