实验步骤: 1-Bromo-3,3,4,4,4-pentafluoro-1-butene may be prepared by a three step sequence beginning with reaction of phosphorous tribromide with 3,3,4,4,4-pentafluoro-1-butanol to give 4-bromo-1,1,1,2,2-pentafluorobutane. Thermal bromination of 4-bromo-1,1,1,2,2-pentafluorobutane at 350-400° C. gives 4,4-dibromo-1,1,1,2,2-pentafluorobutane which may in turn be heated with powdered potassium hydroxide to give the desired bromobutene.
