Versuchsvorschrift

n-Butanol and Cl2 were added concurrently to a 100 ml, four necked, round bottomed flask containing ~10 g of DMF/HCl catalyst and 25 ml of 1,1,2,2-tetrachloroethane. The temperature was maintained between 50° and 55° C. by controlling the rates of the addition. Upon completion of the addition, the reaction mixture was shown to contain mainly the product 2,2-dichlorobutyraldehyde by GC and NMR analysis. Similar results were obtained with isobutanol and 3-phenylpropanol. Analysis was in agreement with authentic products by GC, IR and NMR.
