To a dry 100 mL round-bottom flask containing a magnetic stirbar, under argon, was added 1.79 g (2.1 mmol, 1.0 equiv) [5], CuCl (521 mg, 5.28 mmol, 2.51 equiv), and 25 mL of anhydrous CH2Cl2. Ligand precursor [2] (403 mg, 2.1 mmol, 1.0 equiv) was added to the reddish solution in 20 mL of CH2Cl2 at room temperature. A reflux condenser was added and the mixture was heated for 70 minutes, under argon. The crude product was concentrated and loaded onto silica gel and eluted with 2:1 pentane:CH2Cl2 then 1:1 pentane:CH2Cl2 to remove a dark green band. The column was washed with CH2Cl2, then Et2O. The green and yellow bands were combined and concentrated under reduced pressure to yield a dark green solid.
