Tert-butyl potassium

Potassium tert-butoxide CAS 865-47-4 a vital organic strong base, boasts stronger basicity than potassium hydroxide. Thanks to the inductive effect of the three methyl groups in the (CH₃)₃CO⁻ ion, it exhibits greater basicity and reactivity compared to other alkoxide potassium salts, making it an excellent catalyst available at Chemicalbook.Furthermore, as a strong base, tert-butyl potassium is widely applied in organic synthesis across chemical engineering, pharmaceuticals, agrochemicals and other fields. Typical applications include transesterification, condensation, rearrangement, polymerization, ring-opening reactions, as well as the production of heavy metal orthoesters.

Application Usage:

Potassium tert-butoxide, as a strong alkaline, is widely used in the condensation, rearrangement and ring opening reaction in organic production in the fields of chemical,
It can also be used:
To synthesize aliphatic and aromatic amides from corresponding esters and amines.
As a base in the intramolecular cyclization of aryl ethers, amines, and amides.
As a catalyst to prepare styrene derivatives from aryl halides and alkenes by Mizoroki-Heck reaction.

Strongly basic condensing agent

Potassium tert-butoxide is a strong basic condensing agent, with stronger alkalinity than sodium methoxide and sodium ethoxide. At room temperature, this product is a white or off-white solid powder, with the chemical formula (CH3)3C—O—K, a molecular weight of 112.21, a density of 0.929, a melting point of 256-258℃, and a boiling point of 275℃. It is soluble in tert-butanol, and its solution is relatively stable, often used in the dehydrohalogenation reaction of alkyl halides (Chemicalbook). It decomposes when exposed to air. When it meets water, it decomposes into potassium oxide and tert-butanol.

To prepare potassium tert-butoxide, react tert-butanol with metallic potassium, then distill off tert-butanol under reduced pressure.

Industries widely use it in condensation, rearrangement, ring-opening, and other reactions in organic synthesis—usually in the form of a tert-butanol solution.

Potassium tert-butoxide is an organic basic corrosive substance with high hygroscopicity. You must store it in a sealed container. During storage and transportation, you should take precautions against fire and sun exposure, and keep it in a cool, ventilated, and dry place.
