YieldReaction ConditionsOperation in experiment
63% In methanol; for 24.0h;Reflux; General procedure: The ligands H6L1-7 were prepared by similar methods. A representativemethod for I is presented here. A solution of salicylaldehyde(1.46 g, 12 mmol) in MeOH (30 mL) was added to amethanolic suspension of <strong>[36997-31-6]benzene-1,3,5-tricarbohydrazide</strong>(0.504 g, 2 mmol). The reaction mixture was refluxed on an oilbath. During this period, the <strong>[36997-31-6]benzene-1,3,5-tricarbohydrazide</strong>slowly dissolved and simultaneously a white solid precipitated.After 24 h of reflux, the reaction mixture was cooled at room temperaturefor an hour, the precipitated solid was filtered, washedwith MeOH (2 5 mL) and dried in a desiccator over silica gel.Data for H6L1 (I): Yield 0.954 g (85%). Anal. Calc. for C30H24N6O6(5 6 4): C, 63.83; H, 4.29; N, 14.89. Found: C, 65.31; H, 4.82; N,13.83%. IR data (cm1): 3440 (OAH), 3018 (NAH), 1659 (CO),1563 (CN).
