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:,·
It can also be used as:
- 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.
