Anwendungen

Triisopropylsilylacetylene is used as a reagent for the rhodium-catalyzed asymmetric alkylation of alpha, beta-unsaturated carbonyl compounds as well as in the synthesis of beta-alkynylated nitroalkanes. It is utilized in the preparation of bromoethynyl-triisopropyl-silane in the presence of the reagents such as N-bromo succinimide and silver nitrate. It is actively in involved in Sonogashira coupling reaction with 1-bromo-3-iodo-5-tertbutylbenzene.

Bemerkungen

Incompatible with strong acids, strong bases and strong oxidizing agents.
