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.
