Description

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.
