General description

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.

Application

2,6-Di-tert-butylpyridine was used as proton trapping agent to investigate the living polymerization of isobutylene. It was also used with cerric ammonium nitrate in the α-enolation of aldehydes leading to 1,4-dicarbonyl systems.
