13361-64-3 synthesis

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.

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.]
