用途有機合成原料。

使用2,6-Di-tert-butylpyridine is used in the preparation of 2, 6-di-tert-butylpyridine hydrotriflate. It is used as a proton scavenger to check the progress of the living polymerization of isobutylene. It is associated with cerric ammonium nitrate and used in the alfa-enolation of aldehydes. It is involved in the preparation of vinyl triflate using polymer-bound 2,6-di-tert-butylpyridine.

一般的な説明Reactivity of 2,6-di-tert-butylpyridine with iron(III) tetraphenylporphyrin pi-cation radical has been examined by proton NMR spectroscopy. Reaction of 2,6-di-tert-butylpyridine with methyl iodide and methyl fluorosulfonate under high pressure has been reported.
