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
A solution of Cu(OTf)2 (90.0 mg, 0.249 mM) in methanol was added to a solution of HLpz (53.5 mg, 0.250 mM) and triethylamine (25.0 mg, 0.250 mM) in methanol, affording a dark green solution. A solution of NaN3 (16.3 mg, 0.250 mM) was then layered on the above solution from which blue crystals of 3 suitable for X-ray analysis were obtained (55 mg, 69% yield). Anal. Calcd for C11H9CuN7O: C,41.44; H, 2.85; N, 30.76. Found: C, 40.56; H, 2.77; N, 30.18. UV-vis (CH3OH) [lambdamax, nm(epsilon, M-1 cm-1)]: 354 (5000), 646 (290). FTIR (KBr): 3430, 2055, 1640, 1376, 1164, 1050,866, 769, 660 cm-1. EPR (9.450 GHz, Mod. Amp. 5.0 G, CH3OH, 77 K): g|| = 2.248,g? 2:037, and A|| = 165 G. ESI-MS (MeOH): m/z = 341 [Cu(Lpz)N3 + Na]+, 659{[Cu(Lpz)N3]2 + Na}+, 977 {[Cu(Lpz)N3]3 + Na}+.
With the rapid development of chemical substances, we look forward to future research findings about Copper(II) trifluoromethanesulfonate
