Useful:

• Uses: 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, pharmaceutical and pesticide.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. Usually used for greener amidation of esters. Potassium tert-Butoxide is used in the synthesis of many organic compounds primarily as a strong base. In particular, it is used as a reagent in the base- catalyzed carbonylation of amines for the synthesis of N-Formamides.
