Iminium Ions, Reactions with Acid Chlorides, Reactions with Conjugated Heteroatomic Systems, Reactions of the Triple Bond etc. | [Uses]
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. | [Preparation]
The main method of preparation is shown
in eq 1. The title reagent can be obtained by other methods, but in poor yields. 
| [Purification Methods]
Fractionally distil it and add 2,6-di-tert-butyl-p-cresol (~0.5%) to stabilise it. [Petrov et al. Doklady Acad Nauk USSR 93 293 1953, cf Chem Abstr 48 13616 1954, Beilstein 4 IV 3938.] | [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. |
