Procedure

A mixture of 2-(3-benzylbenzyl)-1,3-dioxolane (8.2 g), acetone (100 cm3), water (10 cm3) and concentrated sulphuric acid (20 drops) was stirred overnight, then added to diethyl ether. The resultant mixture was washed with sodium bicarbonate solution, water and brine, and dried over anhydrous magnesium sulphate. Evaporation of the solvents under reduced pressure gave 3-benzylbenzaldehyde (6.5 g), which was used without further purification.
