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.

Used for greener amidation of esters.
