용도
용도
Iodotrimethylsilane is used for the introduction of trimethylsilyl group in organic synthesis. It is also useful for gas chromatography analysis by converting alcohol into a silyl ether derivative, thereby making it more volatile than the original molecule.Iodotrimethylsilane is a highly efficient reagent for the cleavage of ethers, esters, carbamates, ketals, and lactones. It is also used for the introduction of TMS groups, such as TMS enol ethers, and is a key reagent for the selective removal of N-Cbz groups in the presence of a trimethyltin moiety.This reagent has recently been reported to convert allyl and benzyl phosphotriesters to the corresponding iodides.
일반 설명
Iodotrimethylsilane is a multipurpose reagent used in various organic reactions. It is used for the dealkylation of few compounds like lactones, ethers, acetals, and carbamates and trimethylsilylating agent for the synthesis of silyl imino esters, alkyl and alkenyl silanes, etc. It also acts as a Lewis acid catalyst and as a reducing agent in many organic reactions.
제조 및 합성 방법
제조 방법
Iodotrimethylsilane is prepared by mixing equimolar amounts of chlorotrimethylsilane and sodium iodide in acetonitrile, reduces various benzylic alcohols to the corresponding phenylalkanes. Other have been reported for the preparation of Trimethylsilyl Iodide(TMS-I): chlorotrimethylsilane undergoes halogen exchange with either lithium iodide in CHCl3 or sodium iodide in MeCN, which allows in situ reagent formation. Alternatively, hexamethyldisilane reacts with iodine at 25–61°C to afford TMS-I with no byproducts.
