1066-54-2 Usage


  • Common intermediate for asymmetric synthesis
  • Silica reagent


Ethynyltrimethylsilane was used in: ? microwave-assisted, one-pot, three-step Sonogashira cross-coupling-desilylation-cycloaddition reaction for the preparation of 1,4-disubstituted 1,2,3-triazoles synthesis of poly(ethynyltrimethylsilane) containing Pd (II) coordination sites pyrazole synthesis via 1,3-dipolar cycloaddition of diazo compounds to acetylenes

Silican-protected group

Trimethylsilylacetylene is a silican-protected group, also known as trimethylethynylsilane, trimethylethynyl silicon and ethynyltrimethylsilane. It is a colorless transparent liquid at room temperature. It could be used to synthesize parazole by the addition of 1,3-bipolar ring of acetylene diazide. It is also the substrate of nickel catalyzed reaction and benzonitrile coupling reaction.

Purification Methods

Distil it through an efficient column. The IR has bands at max 2041 (CC) and 3289 (C-H) cm-1. [Kr.hnke & Goss Chem Ber 92 30 1959, Beilstein 4 IV 3937.]
