Introduction | Nickel (II) triflate is a light green powder that can be used as a catalyst, it can be prepared by one-step reaction of nickel acetate and trifluoromethanesulfonic acid. |
Application | Nickel (II) trifluoromethanesulfonate is an organometallic compound, which has been reported to be useful for preparing cathode materials for lithium ion batteries. |
preparation | to Ni(OAc)2(0.519g,2.95 mmol) in MeCN(40 mL) trifluoromethanesulfonic acid (1.33g,8.84 mmol) was added dropwise to the clear green solution in, and the color changed to blue. The mixture was evaporated under reduced pressure until 10ml and diethyl ether (80ml) was added, which resulted in precipitation of a blue powder. The suspension was decanted and the residual powder was washed with diethyl ether and hexane and dried in vacuo at 70 °c to give Nickel (II) trifluoromethanesulfonate, 72%(0.754 g), the color was changed by the light green powder. |
