Reaction Steps

Procedure adapted from Syn. Comm., (1988) 18(9):965-972. A mixture of copper iodide (129 g, 679 mmol), 1-iodo-4-methylbenzene (1) (74 g, 339 mmol) and potassium 2,2,3,3,3-pentafluoropropanoate (120 g, 594 mmol) were dissolved in DMF (500 mL) and heated to 120° C. for 30 minutes and then heated at 160° C. for 4 hours, after which the mixture was allowed to cool to room temperature. Water (200 mL) and ether (200 mL) were added and after stirring for 30 minutes the solids were filtered and washed with ether. The phases were separated and the organic layer was washed with brine/water (3×250 mL). The organic layer was dried and concentrated to yield 1-methyl-4-(perfluoroethyl)benzene (66 g, 92%) as a dark oil.
