TRIFLUOROMETHYLATING AGENT, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING TRIFLUOROMETHYL GROUP-CONTAINING COMPOUND USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a trifluoromethylating agent which is a solid powder, is stable at room temperature, and is highly selective as a reaction reagent.SOLUTION: A trifluoromethylating agent represented by the following general formula (1): Zn(CF)I_(DMF)(wherein DMF is N,N-dimethylformamide, and n is an integer of 1 to 4.) is prepared by reacting a zinc powder and trifluoromethyl iodide in an N,N-dimethylformamide solvent, and thereafter filtering and concentrating the resultant.
