It is a common heterocyclic compound, the copper-catalyst compound, Copper(II) trifluoromethanesulfonate, cas is 34946-82-2 its synthesis route is as follows.
Cu (CF3 SO3 )2 And 4 – (3 – (4H – 1,2, 4 – triazole -4 – yl) phenyl) – 4H – 1,2, 4 – triazole) (L) in a molar ratio of 1:1; L (0.0424 g, 0.2 mmol), Cu (CF3 SO3 )2 (0.0691 g, 0.2 mmol), H2 O (6 ml), CH3 CN (4 ml), water heat 160 o C three days after cooling to room temperature. After operates the cauldron X – ray single crystal diffraction analysis is yellow rod-like crystal. Yield: 35% (calculated on the basis of L). Elemental analysis (C33 H26 Cu3 F9 N18 O10 S3 ) Theoretical value (%): C, 30.67; H, 2.03; N, 19.51. The measured value: C, 30.69; H, 2.06; N, 19.59. We also tried other proportions, for example Cu (CF3 SO3 )2 And L in a molar ratio of 2:1, irrespective of the length of the water heat reaction time, are not crystalline compound. Therefore Cu (CF3 SO3 )2 And L in a molar ratio of 1:1 is the best reaction mixture ratio.
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
