실험 절차

A mixture of 68.0 g. (0.424 mole) of 1-chloro-trans-1-octen-3 one (Example 723) and 444 g. (4.24 moles) of anhydrous lithium bromide in 900 ml. of 2-pentanone is refluxed for 30 minutes, cooled, and partitioned between ice water and either. The organic phase is washed with water and saturated brine, dried (NaSO4), and evaporated to an oil. This material is used directly without purification.
