Iodotrimethylsilane Usage And Synthesis
  • UsesTrimethylsilyliodide is a typical blocking agent in pharmaceutical manufacturing, widely used in the syntheses of drugs. It can protect or deprotect functional groups selectively, act as silane blocking agent.
  • Chemical PropertiesStraw liquid
  • UsesIodotrimethylsilane is an efficient reagent for ether, ester, carbamate, ketal, and lactone cleavage.
  • ReactionsTrimethylsilyl iodide reacts under mild conditions in the absence of a catalyst with alkyl fluorides as well as with benzyl and tertiary alkyl chlorides and bromides to give good yields of alkyl iodides and the corresponding trimethylsilyl halides.
  • Purification MethodsAdd a little antimony powder and fractionate with this powder in the still. 20 1.470. Stabilise the distillate with 1% wt of Cu powder. [Eaborn J Chem Soc 3077 1950, Beilstein 4 IV 4009.]
