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.
