Reaktionsbedingungen

Temperatur: 80 °C

Versuchsvorschrift

A mixture of 279 mg (1.0 mmol) of 1,2-dichloro-1-iodotrifluoroethane, 114 mg (1.0 mmol) of allyltrimethylsilane and 10 mg (0.06 mmol) of azobisisobutyronitrile (AIBN) was heated in a sealed glass tube at 80° C. for 3 hours. After cooling, 10 mg (0.06 mmol) of AIBN was added to the mixture, followed by heating in a sealed tube at 80° C. for 3 hours to obtain 4,5-dichloro-4,5,5-trifluoro-1-pentene (Compound 39) in a yield of 40%.
