용도

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.

참고

Store in a cool place. Incompatible with strong oxidizing agents and strong bases.

Alkylation of the lithio-derivative proceeds with only a small amount of allylic rearrangement to the allene, and is thus a useful route to substituted terminal alkynes: Tetrahedron Lett., 5041 (1968):
