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.

The Stevens rearrangement of N-allylic alpha-aryl amino acid-derived ammonium salts and the Sommelet-Hauser rearrangement of N-benzylic alpha-alkyl amino acid-derived ammonium salts are shown to proceed with remarkably high levels of diastereoselectivity. The methods presented in this work provide new routes

The effects of solvents with different log P values, and of lipases on the synthesis of water-soluble plant stanol derivatives were investigated. Results showed that conversion in solvents with log P<0.37 was mainly controlled by the hydrophobicity of the solvent
