Yield:700-38-9 87% ,2581-34-2 5%

Reaction Conditions:

with silica supported Al(NO3)3*9H2O in acetone at 20; for 0.416667 h;regioselective reaction;

Steps:

Typical Experimental Procedure for the Nitration of Phenol

General procedure: To a solution of phenol (1 mmol) in acetone (5 mL) wasadded silica supported Al(NO3)3·9H2O (1 mmol) and theresulting mixture stirred at room temperature. After completionof the reaction, as indicated by TLC, the reaction masswas filtered and the residue (silica) was washed with ethylacetate (2 5 mL). The filtrate and the washing were collectivelyconcentrated under reduced pressure, and the crudecompound was purified by column chromatography oversilica gel (100-200 mesh) to afford the pure ortho-nitro phenol(95%) and para- nitro phenol (3%).
