Procedure

A stirred mixture of 4.6 grams (0.0179 mole) of 4-chloro-1,1,2-trifluoro-1-dodecene (prepared as in Example 7) and 0.04 gram (0.0003 mole) of alpha, alpha-azobisisobutyronitrile is flushed with argon and 5.1 ml (0.019 mole) of tri-n-butyltin hydride is added dropwise. Upon completion of addition, the reaction mixture is stirred at ambient temperature for 16 hours. The reaction mixture is fractionally distilled under reduced pressure through a Vigreux column. The appropriate fractions are recombined and redistilled, again under reduced pressure and through a Vigreux column. The yield of 1,1,2-trifluoro-1-dodecene is 1.2 grams; b.p. 42°-45° C./0.45mm. The nmr spectrum is consistent with the proposed structure.
