Product Description

(Trimethylsilyl)acetylene, also known as TMS-Acetylene or Ethynyltrimethylsilane, (CAS Number 920-66-1) is one of our most popular compounds.

It is a common intermediate for asymmetric synthesis, and is used in the preparation of trimethylsilanyl-propiolic acid ethyl ester by reacting with carbonochloridic acid ethyl ester.   

(Trimethylsilyl)acetylene is also used in the synthesis of iodoalkenes by radical addition of perfluoroalkyl iodides. 

It is used as a nucleophile in Friedel-Crafts type acylations and alkylations reactions, as a ligand in organometallic chemistry and an useful reagent in cycloaddition reactions.
