Product Application Of Dibutylamine CAS#111-92-2

Dibutylamine is a secondary dialkylamine. It is a versatile intermediate with a variety of applications.
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.
Dibutylamine was employed as organocatalyst during the synthesis of 2-amino-3-cyano-4H-chromen-4-ylphosphonates via Knoevenagel, Pinner and phospha-Michael reactions. Di-n-butylamine (Dibutylamine) may be used to investigate the performance of a dry sampler, with an impregnated denuder in series with a glass fibre filter for airborne isocyanates. It was used in the preparation of 1M dibutylammonium phosphate buffer.
