Sodium Hydroxide → HCID 54070391, compound

Temperature

100 °C

35.9 g of 1,1,7-trichloro-1-fluoroheptane were added to 32.5 ml of NaOH at 50% concentration and 0.65 g of triethylbenzylammonium chloride. Under vigorous stirring, the reaction mixture was heated at 100° C for 20 hours; it was then cooled down and extracted with ethyl ether. The ether solution was neutralized with diluted hydrochloric acid, repeatedly washed with water, dried and finally evaporated. From the distillation of the residue there were obtained 13.4 g of 1,7-dichloro-1-fluoro-1-heptene (1:1 mixture of cis- and trans- isomers) boiling at 40° C/0.2 mm Hg.
