Atropaldehyde diethyl acetal

Atropaldehyde diethyl acetal (8) 1-Propene, 3,3-diethoxy-2-phenyl-... [Pg.6]

B. Atropaldehyde diethyl acetal. A mixture of 18.7 g (0.100 mol) of 1, l-dichloro-2-phenylcyclopropane, 16 g (0.40 mol) of sodium hydroxide, and 160 mL of ethanol is placed in a 250-mL flask fitted with a reflux condenser. The mixture is heated under reflux for 24 hr. Some bumping may occur. Water (200 mL) is added, and the mixture is extracted with three 30-mL portions of petroleum ether. The extracts are combined, dried as above with magnesium sulfate, concentrated in vacuo, and distilled through a 20-cm Vigreux column. The acetal begins to distil at about 70°C (0.5 mm), and the product is collected until the temperature reaches about 100°C. The yield is 14-15 g (68-73%). Gas chromatographic analysis of the product shows it to be about 85% pure (Note 6). [Pg.79]
