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.
