Description

Application

• Dibutylamine is extensively used in palladium-catalyzed cross-coupling with aryl halides to synthesize arylamines, popularly known as Buchwald–Hartwig amination.
• It can be used in the oxone-mediated annulation of 2-aminobenzamides and 1,2-diaminobenzenes to synthesize 2,3-dihydroquinazolin-4(1H)-ones and 1H-benzimidazoles, respectively.
• It can also be used in the one-pot multicomponent reactions to synthesize tetra- and penta-substituted polyfunctional dihydropyrroles.
