Application: Potassium tert-butoxide has been used as a strong base in the enantioselective synthesis of amines by transfer hydrogenation of N-(tertbutylsulfinyl)imines.
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.

Application: Used for greener amidation of esters.

tert-Butoxide-Assisted Amidation of Esters under Green Conditions 

Potassium tert-butoxide may be used as a base in the intramolecular cyclization of iodo arene to afford benzopyran via microwave method of synthesis.
