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