Reaction Steps

700 mg (1.56 mmols) of 2-(2',2',2'-tribromoethyl)-3,3-dimethyl-4-bromocyclobutanone are stirred with a solution of 190 mg of NaOH in 5 ml of water, to which 0.5 ml of dioxane has been added, for 2 hours at room temperature. The mixture is then stirred for 1 hour at 80° C. The clear solution is worked up to the acid in the customary way. 410 mg (88% of theory) of cis-2-(2',2'-dibromovinyl)-3,3-dimethylcyclopropanecarboxylic acid are obtained.
