A new method for the trifluoromethylation of functionalized aromatic diisopropyltriazenes is described. In a facile two-step, one-pot synthesis, various functionalized trifluoromethyl-substituted arenes are accessible in mostly good yields by using methyl iodide as iodination agent and the trifluoromethylation system (trifluoromethyl)trimethylsilane/potassium fluoride/copper iodide. This concept could be expanded to perfluoroethylation as well as ethoxycarbonyldifluoromethylation reactions. Copyright
