詳細

詳細

Butyraldehyde, also known as Butanal, is an aliphatic aldehyde, that is commonly used as a versatile building block in various organic reactions, such as in the synthesis of diverse C4–C8 alcohols, esters, amines, and carboxylic acids.

アプリケーション

Butyraldehyde can be used as a reactant in the:

• Reductive amination of various nitroarene derivatives to synthesize mono-N-alkylated aniline derivatives.
• Ionic liquid-catalyzed Knoevenagel condensation with active methylene compounds to synthesize substituted electrophilic alkenes.
• NiCl₂-catalyzed synthesis of α-aminonitriles by reacting with amines and trimethylsilyl cyanides.
