Reaction Steps
A solution of 23 g of sodium in 1,000 ml of ethanol was added dropwise to 251 g (0.5 mol) of the acetoacetate of 2-methyl-3,5,5,5-tetrabromopentan-2-ol at 0° C. and the mixture was subsequently stirred at 0° C. for 4 hours, then allowed to come to room temperature and concentrated somewhat under reduced pressure. Working up was carried out as in Example 4. 125 g of 2-acetyl-3-(2',2'-dibromovinyl)-4-methyl-γ-valerolactone were obtained, which was processed as described in Example 2.
