Description

General description

Potassium tert-butoxide solution is a strong non nucleophilic base. It is capable of deprotonating carbon and other Bronsted acids. Reagent solutions in tert-BuOh may be prepared by reacting anhydrous alcohol with potassium in nitrogen atmosphere.

Application

Potassium tert-butoxide solution(t-BuOK) can be used:

As a catalyst for the interesterification of rapeseed oil with methyl acetate.
To promote Sommelet–Hauser rearrangements of N-benzylic amino acid-derived ammonium ylides under mild conditions.
As a metal-organic precursor in the synthesis of KNbO₃ ferroelectric films by the chemical vapor deposition method.
To prepare 3-potassiooxamethylpyridine catalyst.
As a strong alkoxide base reagent.
