Application
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.
