1,2,3,4,5-pentachloro-6-fluorobenzene

Conditions: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 144 g (1.5 mol) of fluorobenzene in 1080 ml of 1,2-dichloroethane was admixed with 10 g (0.075 mol) of powdered AlCl3, and 586 g of chlorine gas were then passed into the mixture at 5-15° C. The solution was then stirred at 25° C. for about 5 hours, then heated to 65° C. and 100 ml of water were subsequently added while stirring vigorously. At this temperature, the phases were separated and the organic phase was extracted with water. The solvent was distilled off and the residue was taken up in 1300 g of NMP. After gas-chromatographic analysis (GC), the yield was calculated as: 93.9% of pentachlorofluorobenzene, 4.9% of hexachlorobenzene and 1.1% of tetrachlorofluorobenzenes. The solution can directly be reacted further as described in example 6. were then passed into the mixture at 5-15° C heated to 65° C. while stirring vigorously At this temperature, the phases were separated the organic phase was extracted with water The solvent was distilled off The solution can directly be reacted further

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 400 g (4.17 mol) of fluorobenzene in 2 l of 1,2-dichlorethane was admixed with 53.2 g (0.417 mol) of powdered AlCl3. 1394 g of chlorine gas were subsequently passed into the solution at 0-5° C. After the end of the reaction, the HCl formed was driven out at about 20-25° C. by means of a stream of nitrogen. The reaction solution was admixed with 200 ml of water while stirring vigorously, and the phases were then separated at 50° C. were subsequently passed into the solution at 0-5° C After the end of the reaction
