5,6-Diamino-1,10-phenanthroline was synthesized according to the literature [40]. 5,6-diamino-1,10-phenanthroline (1.20 mmol, 0.25 g) and furoin (1.20 mmol, 0.23 g) were dissolved in 20.0 mL of dimethyl formamide. The mixture was refluxed for 2 days under the atmosphere of nitrogen. dpq-df was collected via filtration and recrystallization by DMF. Yield: 0.25 g, 57percent. 1H NMR [(CD3)2SO]: delta 9.43 (2H, d, J = 8.3 Hz), 9.25 (2H, d, J = 4.8 Hz), 7.98 (4H, m, J = 18.3 Hz), 7.11 (2H, d, J = 3.2 Hz), 6.82 (2H, d, J = 4.7 Hz). Anal. data for C22N4H12O2: calc. (percent): C, 72.52; H, 3.32; N, 15.38. found (percent): C, 72.56; H, 3.31; N, 15.43.

[Cu(CH3CN)4]ClO4 (32.6 mg, 0.100 mmol) was added to adichloromethane (DCM) solution (about 12 mL) of dap (21.4 mg,98percent, 0.100 mmol) and xantphos (59.0 mg, 98percent, 0.100 mmol) undera stream of dry argon by using Schlenk techniques at room temperatureand a vacuum-line system, then orange-red solutionwas obtained quickly and stirred for 1 h at room temperature.The above process can also be carried out in air with the existenceof oxygen. After filtration through absorbent cotton, layeringn-hexane onto the filtrate in air produced the product as orangeredcrystals in 35?44percent yield (39.1?49.3 mg). Anal. Calc. forC52H44Cl3CuN4O5P2 (1aCH2Cl2): C, 60.34; H, 4.29; N, 5.42. Found:C, 60.01; H, 4.34; N, 5.45percent. ESI-MS (m/z): 851.214[Cu(dap)(xantphos)]+ (calcd 851.212); 641.123 [Cu(xantphos)]+(calcd 641.122). 1H NMR (400 MHz, DMSO-d6, delta, ppm): 8.681 (d,2H, J = 8.4 Hz), 8.209 (d, 2H, J = 4.4 Hz), 7.852 (dd, 2H, J = 7.6 Hz,J0 = 1.2 Hz), 7.650 (dd, 2H, J = 8.4 Hz, J0 = 4.4 Hz), 7.252 (t, 6H,J = 7.6 Hz), 7.102 (t, 8H, J = 7.6 Hz), 6.888?6.844 (m, 8H), 6.476?6.438 (m, 2H), 5.758 (s, 2H, CH2Cl2), 5.638 (s, 4H, NH2), 1.745 (s,6H, CH3). 31P{1H} NMR (400 MHz, DMSO-d6, delta, ppm): 13.097.Characteristic IR spectrum (KBr, cm-1): 3444m (NH2), 3372m(NH2), 2969m (CH3), 2925w (CH3), 1101vs (ClO4).

As the paragraph descriping shows that 168646-54-6 is playing an increasingly important role.

168646-54-6, 5,6-Diamino-1,10-phenanthroline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

The reaction and workup steps were performed air-free using standard Schlenk technique or by carrying out manipulations in a N2-filled glovebox. Compound 46 (43 mg, 0.2045 mmol, 1 eq) and Re(CO)5Cl (74 mg, 0.2045 mmol, 1 eq) were suspended in 30 rriL of toluene. The mixture was refluxed for 18 h and then cooled to RT followed by further cooling in an 8 ¡ãC fridge for 30 min. The precipitate was isolated via filtration and washed with hexane to obtain analytically pure product in 88percent yield. 1H-NMR (400 MHz, DMSO-d6) delta (ppm): 9.07 (dd, 2H), 8.90 (dd, 2H), 7.91 (dd, 2H), 5.82(s, 4H). 13C-NMR(150.9 MHz, DMSO-d6) 5 (ppm): 198.15, 190.39, 148.49, 140.17, 132.02, 124.81, 123.90, 123.57.
