Reaction Conditions

Reaction Steps

To 1-benzylphosphorane-1-oxide (4.17 g) were added nitric acid (1.7 ml) and sulfuric acid (11 ml) at 0° C., and the mixture was stirred at 50-60° C. for 2 hours. The reaction mixture was added to crushed ice and neutralized with ammonia solution. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated sodium chloride solution, dried with magnesium sulfate and concentrated. Under reduced pressure, The residue was separated and purified with column chromatography (ethanol/ethyl acetate=1:4→1:1) to give 1-(4-nitro-benzyl)phosphorane-1-oxide (2.22 g) as yellow crystals.
