Beschreibung

Anwendung

2,4-Dinitrophenol (DNP) can be used:

• As a reactant for catalytic reduction reactions.
• To activate carboxylic acids by converting them into dinitrophenyl (DNP) esters.
• To prepare the corresponding ester via acylation reaction using isobutyric anhydride catalyzed by hafnium triflate.
• As an effective cocatalyst to accelerate the activity and enantioselectivity of primary amine organocatalyst derived from natural primary amino acids for direct asymmetric aldol reaction.
• As an alternative activator to tetrazoles in the reaction of phosphoroamidites with nucleosides.
