Reaktionsschritte

Fumic nitric acid (d=1.52, 43.6 g, 0.70 mole) was dropwise added under stirring to 4-benzyloxyphenol (138.0 g, 0.69 mole) in ethylacetate (500 ml) at 0° C. The resulting solution was raised at room temperature and then washed in separatory funnel with sodium hydrogen carbonate in water (saturated solution). The organic layer was separated and evaporated under vacuum and the residual solid was crystallized from methanol (100 ml) to give nitrophenol (Yield of (a): 62.54 g, 36%) as yellow prisms. The product structure was confirmed by NMR and IR spectra.
