Versuchsvorschrift

Under a nitrogen atmosphere, a solution of 5.0 grams (0.027 mole) of undecanoic acid in 75 mL of methylene chloride was stirred and 2.8 ml (0.032 mole) of oxalyl chloride and 5 drops of N,N-dimethylformamide were added. Upon completion of addition, the reaction mixture was stirred for about 16 hours, then it was concentrated under reduced pressure, yielding 2.2 grams of undecanoyl chloride.
