Procedure
To a solution of 2-(2-chlorophenyl)-1-methoxypropene (712 mg, 3.9 mmol) in ether (8 ml) at 0° C. was added perchloric acid (70%, 3 ml). After stirring for 1 h the solution was diluted with ether (8 ml) and washed with water (2×20 ml). The organic phase was separated, dried (Na2SO4) and evaporated. The crude 2-(2-chlorophenyl)propanal was isolated as a colourless oil and used without further purification.
