Reaction Conditions:
with C10H12N2O8(4-)*Cu(2+)*2H4N(1+) in N,N-dimethyl-formamide at 20; for 4 h;Reagent/catalyst;
Steps:
1-23; 1-4
S1,After mixing 5mol of EDTA-copper ammonium complex with 5mol of DMF solvent,Put 1mol of 5-bromo-2-chlorobenzoic acid and trifluoroethanol and mix well,React at 20°C for 4h;
S2,The reaction system in step S1 is diluted with 5ml of water,Then adjust the pH to 6 to precipitate crystals;
S3. The crystals precipitated in the step S2 of separation are 2,5-bis(2,2,2-trifluoroethoxy)benzoic acid.
