34946-82-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Copper(II) trifluoromethanesulfonate, cas is 34946-82-2,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.
Ligand L2/L2? (15.2 mg, 63 mumol) was dissolved in ethylacetate (5 mL) and a solution of Cu(OTf)2 (11.4 mg, 31.5mumol) in ethyl acetate (3 mL) was added. The blue precipitatewas isolated by filtration with suction and dried at air;yield: 26 mg (98%). Crystals suitable for X-ray diffractionanalysis were obtained when a solution of the precipitatein the necessary amount of ethyl acetate was concentratedby slow evaporation. M.p. 255.5-256.5C. – IR (KBr): IR(KBr): = 3259 s br (NH), 3151 w, 1643 m, 1591 s, 1500 m,1285 vs, 1243 vs, ~1228 sh, 1159 s, 1028 vs, 720 m, 636 s,574 w, 518 m cm-1. – MS ((+)-MALDI-TOF): m/z (%) = 694.15(100) [M-CF3SO3]+, 1539.24 (8) [2 [CuL2L2?(OTf)2]-OTf]. -Anal. for C28H30CuF6N10O6S2 (844.27), water-free sample:calcd. C 39.83, H 3.58, N 16.59; S 7.59; found C 39.62, H 3.41,N 16.64, S 7.61.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 34946-82-2, Copper(II) trifluoromethanesulfonate
