    • Cu(ClO4)2·6H2O (0.097 g, 0.262 mmol) was added to a solution of L1 (0.150 g, 0.524 mmol) in 10 mL of MeOH and stirred for 2 h. The solution was filtered. The filtrate was evaporated to dryness and washed with diethyl ether. The solid obtained was recrystallized from MeOH to obtain [1]ClO4 as dark-orange crystals. Yield: 65 mg. Metathesis: KSCN (0.016 g, 0.169 mmol) was added to a methanolic solution of [1]ClO4 (0.050 g, 0.169 mmol, The solution was stirred for 20 min and filtered to remove undissolved KClO 4. A dark-brown crystalline product was obtained from slow evaporation of the filtrate. Yield: 30 mg. Characterization data for [1]ClO4. Anal. Calcd for C12H10N 3ClO4: C, 48.80; H, 3.41; N, 14.24.
