일반 설명
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.
애플리케이션
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 regio- and diastereoselective silaboration of aromatic alkenes with a silylboron compound proceeds in the presence of a catalytic amount of potassium tert-butoxide, providing a complementary method to the corresponding transition metal-catalyzed reactions.

3-Aryltetronic acids were prepared in one step by treatment of a mixture of methyl arylacetates and methyl hydroxyacetates with potassium tert-butoxide, via tandem transesterification/Dieckmann condensation. Several mushroom or lichen pigments, vulpinic acids, were synthesized from 3-(4-methoxyphenyl)tetronic acid in three steps
