1,6-Diiodoperfluorohexane

Conditions: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 26.64 g of p-fluoroiodobenzene, 100 ml of DMSO and 15.24 g of copper powder were put in a flask under an atmosphere of nitrogen to be sufficiently stirred at a temperature of 110° C. Next, 30.46 g of 1,6-diiodoperfluorohexane was slowly dropped and stirred at a temperature of 120° C. for 20 hours. Then, the reaction solution was filtered so as to remove the unreacted copper, and was dropped into an aqueous solution containing a small quantity of NaCl. Then, the resulting deposits were filtered. The deposits were dissolved in acetone to be filtered and thereafter distill out the acetone. The residue was dissolved in methanol to add water and deposits were filtered. The deposits were distilled at a reduced pressure (155° C., 5 mmHg), thereby obtaining 20 g of a colorless solid. stirred at a temperature of 120° C. for 20 hours Then, the reaction solution was filtered so as to remove the unreacted copper was dropped into an aqueous solution containing a small quantity of NaCl Then, the resulting deposits were filtered The deposits were dissolved in acetone to be filtered distill out the acetone The residue was dissolved in methanol to add water and deposits were filtered The deposits were distilled at a reduced pressure (155° C., 5 mmHg)
