Description
Crystal structure and IRl data for Bis(ethanol) bis((4-benzoyl-1-(4-methoxybenzyl)-1H-pyrazol-5-yl)oxy)copper (55): Cu(OAc)2•H2O (43.0mg, 0.216 mmol, 1.00 equiv) was added with stirring to pyrazolone 10 (133 mg, 0.431 mmol, 2.00 equiv) in EtOH (3.5 mL) at 79 °C. After 2 h at reflux, the mixture was cooled to room temperature, and the resultant precipitate was collected by filtration and dried in vacuo. Cu-pyrazolone complex 55 (124 mg, 0.161 mmol, 75%) was obtained as a brown solid. Crystals suitable for X-ray crystallography were obtained by slow evaporation from an EtOH solution of complex 55. IR (Diamond-ATR, neat) νmax (cm-1) = 1594, 1573, 1530, 1511, 1503, 1487, 1438, 1392, 1321, 1286, 1240, 1172, 1026, 902, 804, 796, 754, 699. HRMS (ES-ToF) m/z: [M – Solvent + H]+ calc. for (C36H31CuN4O6)+: 678.1534, found: 678.1542. m.p.: 211 – 214 °C (EtOH). Anal. Calcd for C36H30CuN4O6: C, 63.76; H, 4.46; N, 8.26. Found: C, 63.56; H, 4.46; N, 8.18.
