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.
To a yellow-brown solution of L1 (60 mg, 0.09 mmol) in THF (3 mL)was added a blue solution of [Cu(OTf)2] (36 mg, 0.09 mmol) at roomtemperature. Upon addition the solution colored to dark green. Themixture solution was stirred for 8 h and after filtered, 20 mL of diethylether were then added to the filtrate to precipitate a green solid. Thesolvents were removed by filtration and the residue was washed withether (3¡Á5 mL) and dried in vacuum to yield product 3 as a blue-greenpowder. The formulation of 3 was deduced from elemental analysis asbeing [Cu(H2O)2(L1)](OTf)2, H2O. Yield: 50 mg, 56%. Crystals suitablefor a X-ray diffraction study were obtained by slow vapor diffusion ofEt2O into a CH3CN solution of 3 in a sealed tube.
