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

摘要

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) (CF)Zn (DMPU)(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.
