As a common heterocyclic compound, it belongs to copper-catalyst compound, name is Copper(II) trifluoromethanesulfonate, and cas is 34946-82-2, its synthesis route is as follows.,34946-82-2

General procedure: Representative procedure for 17: A Schlenk tube was charged with 2 (400mg, 2.03mmol), dry THF (10mL), anhydrous cobalt(II) chloride and a stirring bar. In a separate Schlenk tube, a solution of lithium diisopropylamide (LDA) was prepared in THF (25mL) from diisopropylamine (700muL, 5.0 mmol) and n-butyl lithium (3.15mL of a 1.6M solution in hexane, 5.0 mmol). The LDA-solution was added under protection from air to the solution of 2 and CoCl2. After the mixture has been stirred overnight, all volatile materials were removed on a vacuum line. The Schlenk vessel was transferred into the glove-box and the dark colored solid residue was dissolved in a small volume of dry dichloromethane. Layering the solution with dry n-hexane afforded brown single crystals of the product.
