1662-01-7, 4,7-Diphenyl-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The chloro-bridged dimeric iridium complex[Ir(ppz)2Cl]2 (123 mg, 0.12 mmol) and 4,7-diphenyl-1,10-phenanthroline (88 mg, 0.26 mmol) were dissolved in CH2Cl2 (15 ml) and MeOH (15 ml). The mixture was refluxed under nitrogen for 12 h and the yellow solution obtained was cooled to room temperature and solid ammonium tetrafluoroborate (52 mg, 0.5 mmol) was added to it. The reaction mixture was stirred at room temperature for 1 h and the solvent was evaporated under vacuum. The product obtained was dissolved in dichloromethane, filtered to remove the unwanted inorganic impurities, and then precipitated with hexane. The crude material obtained was purified by column chromatography (Merck Alox 90; CH2Cl2 changing toCH2Cl2/MeOH, 100:2) yielding the desired product as yellow solid (156 mg, 0.17 mmol,73%). The chemical structure of the cationic iridium complex is shown in Fig. 1. 1H NMR(500 MHz, CD2Cl2) delta (ppm): 8.50 (d, J = 5.2 Hz, 2H), 8.13 (d, J = 3.1 Hz, 2H), 7.66 (d, J = 5.1 Hz, 2H), 7.61-7.54 (m, 4H), 7.33 (d, J = 7.1 Hz, 2H), 7.26 (d, J = 2.93 Hz, 2H),7.11-7.07 (m, 4H), 6.98-6.92 (m, 4H), 6.54 (t, 5.1 Hz, 1H), 6.48-6.46 (m, 1H). 13C NMR(126 MHz, CD2Cl2) delta (ppm): 151.6, 150.8, 148.3, 143.5, 139.0, 135.8, 130.3, 129.9, 129.7,129.4, 127.2, 126.9, 126.5, 123.6, 121.7, 111.7, 108.7.
