Reaktionsschritte
A solution of acetyl chloride (43.2 g, 550 mmol) in 100 mL of dry ether was added dropwise over 1 hour to a solution of 1,3 dioxolane (37.1 g, 500 mmol) in 300 mL of ether containing a few crystals of zinc (II) chloride at room temperature under nitrogen. The reaction mixture was stirred at room temperature for an additional 2 hours and then concentrated in vacuo. The product was purified by distillation (0.6 mmHg, 56°-58° C.) to provide 67.9 g (89%) of 1-acetoxy-2-(chloromethoxy)ethane as a clear colorless oil. cf: Foye, W. O.; Kaufmann, J. M.; Kim, Y. H. J. Heterocyclic Chem. 1987, 19, 497.
