Description
Bis(ethanol) bis((4-(ethoxycarbonyl)-1H-pyrazol-5-yl)oxy)manganese (44: Mn(OAc)2 (64.0 mg, 0.368 mmol, 1.00 equiv) was added with stirring to pyrazolone 5 (115 mg, 0.737 mmol, 2.00 equiv) in EtOH (6.5 mL) at 79 °C. The mixture was heated at reflux for 18 h, cooled to room temperature, Et2O was added (15 mL), and the precipitate was collected by filtration and dried in vacuo. Mn-pyrazolone complex 44 (99.0 mg, 0.216 mmol, 59%) was obtained as a pale-pink solid. Crystals suitable for X-ray crystallography were obtained by slow evaporation from an EtOH solution of complex 44. IR (Diamond-ATR, neat) νmax (cm-1) = 3336, 1663, 1638, 1545, 1525, 1435, 1319, 1269, 1172, 1118, 1061, 928, 787, 753. m.p.: >230 °C (EtOH) (decomp.).
