Trifluoroacetic anhydride 51.9 g (0.247 mole) was added in one portion when the pot temperature was 10° C. Hydrogen peroxide solution (50%) 6.9 g (0.101 mole) was then added in several portions. The exotherm raised the pot temperature to 32° C. The reaction mixture was then chilled to 80° C. A solution of 2,3-bischloromethyl-1,4-dichloro-2-butene 5.6 g (25.6 m moles) in methylene chloride 30 ml was added dropwise over a twenty-minute period. The resulting reaction mixture was warmed to ambient temperature for three hours and refluxed for five hours.
