General procedure: To a 50 mL Schlenk flask, 200 mg (0.35 mmol) H4L2, 310 mg(0.86 mmol) of Cu(OTf)2, and 20 mL of dry CH3CN were added and theresulting mixture allowed to stir for 10 min. To the suspension, 1.0 mLof a 2.18M solution of NMe4OH in MeOH was added, resulting in acolor change to a deep green. After stirring for 1 h, solvent was removedunder vacuum to bring the volume to?5 mL. Diethyl ether (20 mL)was added, resulting in the precipitation of green powder that wascollected by filtration, washed with Et2O (2 x 20 mL) and allowed to dry(96 mg, 33%).
