Use
Potassium tert-butoxide is an important kind of organic base with its alkalinity being stronger than potassium hydroxide. because of the induction effect of three methyl groups in the (ch3) 3co-, it has stronger alkalinity and activity than other potassium alkoxides, thus being a very excellent catalyst. in addition, as a kind of strong alkaline, potassium tert-butoxide is widely used in the organic synthesis of chemical, pharmaceutical, and pesticide such as trans-esterification, condensation, rearrangement, polymerization, loop opening and the production of heavy metal orthoester. Potassium tert-butoxide can be used to catalyze the michael addition reaction, pinacol rearrangement reaction and ramberg-backlund rearrangement reaction. potassium tert-butoxide is used as a condensing agent, which can be used to catalyze darzens condensation reaction and stobbe condensation reaction.
