Potassium tert-butoxide CAS 865-47-4

What is Potassium tert-butoxide CAS 865-47-4？

Potassium tert-butoxide is an important organic base with a higher alkalinity than potassium hydroxide. Due to the inductive effect of the three methyl groups of (CH3)3CO-, it has stronger alkalinity and activity than other potassium alcoholates, so it is a good catalyst. In addition, as a strong base, potassium tert-butoxide is widely used in organic synthesis such as chemical industry, medicine, pesticide, etc., such as transesterification, condensation, rearrangement, polymerization, ring opening and the production of heavy metal orthoesters. It can be used to catalyze Michael addition reaction, Pinacol rearrangement reaction and Ramberg-Backlund rearrangement reaction; potassium tert-butoxide is used as a condensation agent to catalyze Darzens condensation reaction and Stobbe condensation reaction; it is also the most effective base for the traditional alkoxide-haloform reaction to generate dihalocarbene. Therefore, potassium tert-butoxide is increasingly favored by the chemical industry, medicine, pesticide and other industries. Potassium tert-butoxide has such a wide range of uses, so there is a large demand for high-purity potassium tert-butoxide at home and abroad. However, since its production cost is higher than that of other alkali metal alcoholates and its production technology needs to be improved, in-depth research on potassium tert-butoxide is particularly important.
