General description

Iodotrimethylsilane [(CH3)3SiI] is an important and versatile organosilicon reagent with wide applications in organic synthesis. It is used as a neutral nucleophilic reagent, trimethylsilylating agent, Lewis acid catalyst, reducing agent and dehydrating agent in many organic reactions.

Application

Iodotrimethylsilane can be used as:
  • A reagent in the hydroiodation of ynamides to yield the important building blocks (E)-α-iodoenamides.
  • A reagent in the synthesis of (1-iodovinyl) arenes by hydroiodation of trimethylsilyl ethynylarenes.
