Kawasaki-Takasuka, Tomoko published the artcileThe modified trifluoromethylation protocol applicable to electronically deficient iodopyridinones, Computed Properties of 197958-29-5, the publication is Tetrahedron (2015), 71(38), 6824-6831, database is CAplus.
Utilization of a mixed solvent system of DMF/HMPA = 1/1 (volume/volume) to the KF/CuI/TMSCF3 reagent system proved to significantly affect the reaction, realizing convenient introduction of a trifluoromethyl (CF3) group not only to electron-deficient iodopyridinones, e.g., I, with quite a few previous successful examples but also to aliphatic vinylic iodides such as 2-iodocyclohex-2-en-1-one, 1-iodocyclohex-1-ene, (E)- and (Z)-(4-iodobut-3-en-1-yl)benzene.
