Versuchsvorschrift

Salen ligand (C0) (1.0 g, 3.9 mmol) and aluminium triethoxide (1.2 g, 7.4 mmol) were dissolved in dry toluene (25 mL). The reaction mixture was refluxed for 4 hours after which the toluene was evaporated and the resulting yellow residue taken up in dichloromethane and washed with water (3×100 mL) and saturated brine (100 mL). After evaporation of the organic phase, a light yellow powder was obtained which was washed with diethyl ether (ca. 50 mL) and dried to give salen complex (C1) (1.2 g, 49%). 1H NMR 3.87 (8H, s, 2×CH2CH2), 6.7-6.9 (8H, m, 8×HAr), 7.1-7.3 (8H, m, 8×HAr), 8.29 (4H, s, 4×CHN). 13C NMR 60.14, 65.09, 117.36, 119.00, 131.81, 132.74, 161.46, 166.85. m/z (ESI) Found: 603.1775 C32H25N4O5Al2 (MH+), Requires 603.1769.
