Demonstrates high reactivity of copper(III) complexes in trifluoromethylation of uracil derivatives, suggesting potential applications in organic chemistry.
The first scorpionate complexes of high-valent copper(III) TpCu(CF3)2 and Tp*Cu(CF3)2 were synthesized by a ligand exchange reaction of the acetylacetonate complex (acac)Cu(CF3)2 and fully characterized. The structure, effective oxidation state of copper, natural charge distribution and photochemical properties of these compounds were studied by DFT calculations. The presence of copper in the +3 oxidation state was supported by XPS spectroscopy. TpCu(CF3)2 is a bench-stable solid and exhibits high reactivity in trifluoromethylation of uracil derivatives under photochemical conditions.
