4-nitroperoxybenzoic acid Chemical Properties,Uses,Production
Uses
4-Nitroperoxybenzoic acid is an electrophile that transfers oxygen to alkenes.
Preparation
The reaction between Na2O2 and p-Nitrobenzoyl Chloride in THF in the presence of small quantities of water below -5 °C furnishes the sodium salt of PNPBA. p,p′- Dinitrobenzoyl peroxide and p-nitrobenzoic acid are removed from the reaction mixture during workup. PNPBA (purity 94-96%) is obtained in 85% yield (0.1 mol scale).
Production Methods
This peroxide can be prepared from p-nitrobenzoic acid and 90% hydrogen peroxide in methanesulfonic acid medium.
