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
For the synthesis of (I), a solution of BDPA (0.160 g,0.554 mmol) in THF (6.0 ml) was added to a solution of Cu(triflate)2 (0.200 g, 0.554 mmol) in THF (6.0 ml) and theresulting mixture was stirred for 12 h. The resulting palegreen-palegreen-blue solution was concentrated under reduced pressure,affording a pale-green-blue solid which was dried under high vacuum. The solid was dissolved in THF and diffused withdiethyl ether, giving blue block-shaped crystals after 5 d(yield: 0.102 g, 26%). Elemental analysis calculated: C 40.51,H 3.94, N 5.67, S 8.65%; found: C 40.31, H 3.79, N 5.62; S8.69%. FT-IR (KBr, cm-1); 3374 (m), 3092 (w), 3030 (w), 2965(w), 2969 (m), 2880 (w), 1657 (m), 1612 (s), 1484 (m), 1450 (s),1358 (w), 1288 (s), 1250 (s), 1168 (s), 1030 (s), 860 (m), 771(m), 706 (m), 635 (s).
With the rapid development of chemical substances, we look forward to future research findings about Copper(II) trifluoromethanesulfonate
