Copper(II) trifluoromethanesulfonate, cas is 34946-82-2, it is a common heterocyclic compound, the copper-catalyst compound, its synthesis route is as follows.,34946-82-2
Copper(II) trifluoromethanesulfonate (5 g, 14 mmol) was dissolved in methanol (25 mL). Pyridine(12 mL, 149 mmol) was added dropwise (exothermic reaction was observed) and the reaction mixturewas stirred for 30 min. The mixture was left at ambient temperature for 1 h and thereafter in fridge (at5 C) overnight. The blue crystalline precipitate was filtered off, recrystallized from 20% Py in MeOHand dried under a stream of air affording the desired product [56]. Yield 8.5 g, 91%Appearance blue solidMolecular formula C22H20CuF6N4O6S2Molar mass 678.08042Anal.Calcd for C22H20CuF6N4O6S2: C, 38.97; H, 2.97; N, 8.26. Found: C,39.1 < 0.1; H, 3.16 0.09; N, 8.33 0.01.
With the rapid development of chemical substances, we look forward to future research findings about 34946-82-2
