Applications
(Trimethylsilyl)acetylene is used in the preparation of trimethylsilanyl-propiolic acid ethyl ester by reacting with carbonochloridic acid ethyl ester as well as 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. It acts as a precursor to lithium trimethylsilylacetylide It finds application in the synthesis of (±)-estrone.

Solubility
Miscible with organic solvents.

Notes
Store in a cool place. Incompatible with strong oxidizing agents.
