General description

Trimethyl(propargyl)silane (2-Propynyl-trimethylsilane) is a clear colorless liquid and contains 500ppm of butylated hydroxytoluene (BHT) as stabilizer. It undergoes GaCl3-catalyzed dehydrogenation reaction with aldimines to afford 4-methylquinoline.

Application

Trimethyl(propargyl)silane is suitable for use in the synthesis of diverse end-functionalized (ω-carboxyl, ω-hydroxy, ω-methyl-vinyl, ω-trimethylsilane, and ω-glycidyl-ether) via ′′click′′ reaction. It may be used in the synthesis of γ-allenyl-GABA (γ-aminobutyric acid), via Lewis acid mediated reaction with ω-ethoxy lactams.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
