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.
A saturated solution of Cu(OTf)2 in n-butanol was addeddrop by drop to a solution of ligand L5 (40 mg, 0.16 mmol) in n-butanol (3 mL). Diethyl ether was placed on top of theblue butanol layer. After several weeks, deep blue crystalplatelets separated which were isolated by filtration withsuction, washed with a small volume of diethyl ether anddried at air. Yield: 64 mg (91); M.p. 271-275C. – IR (KBr): = 3322 br, 3154 w br, 3063 w, 1641 m, 1613 s, 1453 m, 1284vs, 1256 vs, 1225 vs, 1167 s, 1032 vs, 759 m, 700 s, 639 vs,576 m, 518 m cm-1. – Anal. for C28H30CuF6N10O6S2 (844.27):calcd. C 39.83, H 3.58, N 16.59; found C 40.07, H 3.74, N 16.16.
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
