Versuchsvorschrift

Instead of (-)-2-ethyl-1-octanol in Example 8, 5.07 g (25.3 mmol) of (-)-2-propyl-1-decanol was used and then oxidized with potassium permanganate under the same acidic state of sulfuric acid as in Example 6 to obtain 2-propyl decanoic acid. 2.19 g (10.2 mmol) of this compound was reacted with 1.75 g (14.7 mmol) of thionyl chloride under the same conditions as in Example 8 to obtain 2.39 g of a light brown liquid of (+)-2-propyldecanoic acid chloride having a specific rotation [α]25 of +1.63.
