BIS(TRIFLUOROMETHYL)ZINC DMPU COMPLEX, MANUFACTURING METHOD THEREOF AND MANUFACTURING METHOD OF TRIFLUOROMETHYL GROUP-CONTAINING COMPOUND USING THE SAME

PROBLEM TO BE SOLVED: To provide a bis(trifluoromethyl)zinc DMPU complex stable under room temperature and useful as a reaction reagent, a manufacturing method thereof and a manufacturing method of a trifluoromethyl group-containing compound using the same. SOLUTION: A method of obtaining a trifluoromethyl group-containing compound by reacting with a substituted aromatic iodide under a copper (I) catalyst after obtaining a bis(fluoromethyl)zinc DMPU complex represented by the formula (1) (CF3)2Zn (DMPU)2 (1), where DMPU represents N,N'-dimethyl propylene urea, by reacting dialkyl zinc, trifluoromethyl halide and N,N'-dimethyl propylene urea in an organic solvent, then filtration or solvent leaving removal of precipitate.

Stable but reactive perfluoroalkylzinc reagents: Application in ligand-free copper-catalyzed perfluoroalkylation of aryl iodides

The aromatic perfluoroalkylation catalyzed by a copper(I) salt with bis(perfluoroalkyl)zinc reagents Zn(RF)2(DMPU)2, which were prepared and then isolated as a stable white powder from perfluoroalkyl iodide and diethylzinc, was accomplished to provide the perfluoroalkylated products in good-to-excellent yields. The advantages of this reliable and practical catalytic reaction are 1) airstable and easy-to-handle bis(perfluoroalkyl)zinc reagents can be utilized, 2) the reagent is reactive and hence the operation without activators and ligands is simple, and 3) not only trifluoromethylation but also perfluoroalkylation can be attained.

Me3SiCF3/AgF/Cu - A new reagents combination for selective trifluoromethylation of various organic halides by trifluoromethylcopper, CuCF3

An alternative copper halide-free route to obtain highly reactive trifluoromethylcopper species has been developed via the reaction of silver fluoride and trimethyl(trifluoromethyl)silane followed by a redox transmetallation with elemental copper. The composition of the reactive intermediate was investigated by means of UV/Vis/NIR, ESR, 19F NMR spectroscopy and ESI mass spectrometry. "Trifluoromethylcopper" prepared by the oxidative transmetallation route exhibits excellent reactivity and selectivity in substitutions of iodine or bromine bond to aromatic or heterocyclic compounds for trifluoromethyl groups without any additional catalyst.
