DIBUTYLAMINE >=99.5% (C005B-008788)

General description

Dibutylamine is a highly reactive catalyst, commonly used as a reagent in the derivatization of isocyanates.

Application

Dibutylamine can be used as a reactant to synthesize:,·      

• N, N

• -Dibutyl-4-methylaniline by Pd-catalyzed Buchwald-Hartwig amination reaction with aryl chlorides and bromides.     
• N,N-Dibutylacetamide by acetylation reaction with isopropenyl acetate.

It can also be used as:      

• A strong hindered base in the different elimination reactions.
• An organocatalyst to synthesize annulated pyrano[2,3-d]pyrimidine derivatives via multicomponent condensation reaction of aromatic aldehydes, malononitrile, and barbituric acid.
