The Uses of 2,6-DI-TERT-BUTYLPYRIDINE

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.

The Uses of 2,6-DI-TERT-BUTYLPYRIDINE

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.

What are the applications of Application

2,6-Di-tert-butylpyridine is a proton trap for living carbocationic polymerization

Definition
