General description
Application
- As a catalyst in the aldol condensation of aldehydes with ketones in the synthesis of chalcone and azachalcone.
- As a pH stabilizer agent in the synthesis of FeO-NPs (iron oxide nanoparticles) in the presence of cymbopogon citratus as a reducing agent.
- As a base in the Pd-catalyzed Suzuki coupling reactions.
- As a base in the transition metal free Suzuki coupling reaction of aryl halides and arylboronic acids to form biaryls using water as a solvent and TBAB (tetrabutylammonium bromide) as a phase-transfer catalyst.
