In a manner similar to Example 13A, the reaction of 25.0 g (0.12 mole) of (+)-trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic acid, 180 ml of toluene, and 30.4 g (0.24 mole) of oxalyl chloride gave 25.8 g of (+)-trans-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarbonyl chloride. The nmr spectrum was consistent with the proposed structure.
