Potassium tert-butoxide

Chinese name:叔丁醇钾

CAS number 865-47-4

Molecular weight 112.21

Potassium tert butanol is an important organic base with greater alkalinity than potassium hydroxide. Due to the induction effect of (CH3) 3CO trimethyl, it has stronger alkalinity and activity than other potassium alcohols, making it a good catalyst. In addition, as a strong base, potassium tert butanol is widely used in organic synthesis such as chemical, pharmaceutical, pesticide, etc., such as ester exchange, condensation, rearrangement, polymerization, ring opening, and the production of heavy metal orthoesters. It can be used to catalyze Michael addition reactions, Pinacol rearrangement reactions, and Ramberg Backlund rearrangement reactions; Potassium tert butanol can be used as a condensation agent to catalyze Darzens condensation reactions and Stobbe condensation reactions; It is also the most effective base for the traditional alcohol salt haloform reaction that generates dihalogenated carbenes. Therefore, potassium tert butanol is increasingly favored by industries such as chemical, pharmaceutical, and pesticide industries.
