In a manner similar to Example 13A, the reaction of 13.0 g (0.0436 mole) of (+)-cis-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylic acid, 50 ml of toluene, and 11.1 g (0.0873 mole) of oxalyl chloride gave 7.0 g of (+)-cis-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarbonyl chloride. The nmr spectrum was consistent with the proposed structure.
