1-Trimethylsilyl-1-propyne is employed in the preparation of alkynyl silane derivatives. It is also used to prepare highly substituted indenes using palladium-catalyzed carboannulation. Further, it plays an important role in the preparation of indenones through a rhodium-catalyzed reaction with 2-bromophenylboronic acids.

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.
