Name is Copper(II) trifluoromethanesulfonate, as a common heterocyclic compound, it belongs to copper-catalyst compound, and cas is 34946-82-2, its synthesis route is as follows.
In a 20 mL vial with heating, anhydrous copper(II) trifluoromethanesulfonate(221 mg, 0.61 mmol) was dissolved in 15 mL of90% EtOH. After cooling to room temperature, HL1 (200 mg,0.61 mmol) was added to the pale blue solution, which became bluegreen.The mixture was heated to boiling to ensure all reactants weredissolved, and then cooled to room temperature, at which point thesolution was green-blue and contained a teal precipitate. The precipitatewas isolated via gravity filtration as a bright teal powder (256 mg, 71%). HR-MS (ESI, MeOH) m/z: [L1Cu]+ Calcd. for[CuC20H12N3O2]+ 389.0226; found 388.9763; m/z [L1CuII(EtOH)]+Calcd. for [CuC32H18N3O3]+ 435.0644; found 435.0132 (Fig. S4). Anal.Calc. for CuC21H14N3O6SF3: C, 45.29; H, 2.53; N, 7.54. Found: C, 45.06;H, 2.74; N, 8.09. X-ray quality crystals in the form of teal blocks weregrown upon slow diffusion of anhydrous THF into a concentrated solutionof the compound in EtOH at room temperature.
34946-82-2, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,34946-82-2 ,Copper(II) trifluoromethanesulfonate, other downstream synthetic routes, hurry up and to see
