It is a common heterocyclic compound, the copper-catalyst compound, Copper(II) trifluoromethanesulfonate, cas is 34946-82-2 its synthesis route is as follows.
The ligand (75.9 mg, 0.12 mmol) was dissolved in THF (4 ml) and added to a suspension of sodium hydride (11.8 mg, 0.49 mmol) in THF (2 ml) at 0 C. The resulting yellow mixture was stirred at 0 C for 1 h and at r. t. for 2 h. Afterwards the solution was added dropwise to a solution of copper(II) triflate (44.3 mg, 0.12 mmol) in THF (2 ml). The dark brown solution was stirred at r. t. for 16 h. After filtration the solvent was removed in vacuo and the brown solid purified by recrystallisation from dichloromethane and pentane. 6: 60.8 mg, 60.9%. C41H36N5O5SF3Cu¡¤3CH2Cl2: Anal. Calc. C, 46.35; H, 4.24; N, 6.14. Found: C, 46.70; H, 4.12; N, 6.19%. HR-MS: C40H36N5O2Cu Calc. 681.2159. Found: 681.2148 (100.0), IR: nunu [cm-1]=3060, 2929, 2855, 1640, 1592, 1530, 1444, 1262, 1174, 1097, 1044, 879, 646.
