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:
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.
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.
