실험 절차
To a solution of 15.0 g (0.074 mole) 1,2-dichloro-3-(2-methoxyethenyl)benzene in 150 ml of THF was added 15 ml of 35% perchloric acid in water. The reaction was refluxed for 3.5 hr then poured into ice/water. The aqueous layer was extracted two times with ether, the organics were washed with water, brine and dried (MgSO4). Evaporation of the solvent gave 13.91 g of crude 2,3-dichlorobenzeneacetaldehyde a yellow oil (99%).
