High-valent Cu(III) trifluoromethyl complexes with 1,3-diketonates as bidentate oxygen donor ligands LCu(III)(CF3)2 were prepared for the first time and fully characterized, including by X-ray crystallography. These complexes are bench stable and soluble in most organic solvents. Promising reactivity of Cu(III) trifluoromethyl diketonates in radical and radical-polar crossover trifluoromethylation

Using a reaction medium containing nanoparticles consisting of commercially available TPGS-750-M in water, a combination of Langlois’ reagent and t-BuOOH can be used to effect trifluoromethylation of several heterocyclic arrays, including heteroaromatics. These reactions take place at ambient temperatures, and the aqueous medium can be recycled.
