With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.34946-82-2,Copper(II) trifluoromethanesulfonate,as a common compound, the synthetic route is as follows.

General procedure: The solution of CuX2 salt (0.5 mmol, 120.8 mg of Cu(NO3)23H2Ofor 3a/b and 180.8 mg of Cu(CF3SO3)2 for 4) in 5.0 mL of ethanol (3aand 4) or methanol (3b) was mixed with the solution of anequimolar amount of 1,7-phen (90.1 mg) in 5.0 mL of ethanol (3aand 4) or methanol (3b). After addition of 1,7-phen, a solutionchanged color from blue to green, and no formation of metalliccopper was observed. The reaction mixture was stirred at roomtemperature for 3-4 h and then left at room temperature to slowlyevaporate. Crystals of compounds 3a/b were obtained from themother solution, while those of compound 4 were obtained after recrystallization of the solid product formed from the reactionmixture in 15.0 mL of acetonitrile. These crystals were filtered offand dried at ambient temperature. Yield (calculated on the basisof 1,7-phen): 65.7 mg (54%) for 3a, 74.2 mg (61%) for 3b and94.1 mg (57%) for 4.
