Description

Description

(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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
