DIIODOSILANE Usage And Synthesis

Chemical Properties

Clear liquid

Uses

Reagent involved in reductive iodination for synthesis of [18F]FDOPA

Preparation

Preparative Method of Diiodosilane: phenylsilane and iodine are mixed in a 1:1 molar ratio without solvent at -20 °C in the presence of catalytic amounts of ethyl acetate; fractional distillation removes volatile side products (benzene and HI) and affords the reagent in the form of a colorless oil.

General Description

Diiodosilane (DIS) is a strong, oxophilic Lewis acid, converts alcohols, ethers, and acetals to iodoalkanes; converts carboxylic acid derivatives to acyl iodides; mild reducing agent.

storage

Diiodosilane is sensitive to moisture; handle and store under nitrogen; stabilized by metallic copper; refrigeration and absence of light recommended for storage over long periods of time.
