The reaction conditions
employed (trifluoromethyl)trimethylsilane (2) (Me3SiCF3, çRuppert-Prakash reagenté) as
trifluoromethyl source. Under the optimized reaction conditions using 1.0 equiv of aryl
iodide and 2.0 equiv of Me3SiCF3 in the presence of 10 mol% of CuI, 20 mol% of
N,Nû-dimethylethylenediamine (dmeda), 20 mol% of NaOt-Bu, and 1.35 equiv of AgF in
N-methylpyrrolidone (NMP) at 90°C for 6 hours, trifluoromethylation of aryl iodide was
achieved with a broad substrate scope (Table 1).
