With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1662-01-7,4,7-Diphenyl-1,10-phenanthroline,as a common compound, the synthetic route is as follows.
[CuI(MeCN)4](ClO4) (50mg, 0.15mmol), PPh3 (80.4mg, 0.30mmol) and Ph2Phen (55.9mg, 0.17mmol) in MeCN (15ml) are stirred at room temperature for 1h. Slow evaporation of a MeCN solution of 3 afforded analytically pure complex as yellow crystalline solid. Yield (93.1mg, 59.8%). Elemental analysis for C60H46ClCuN2O4P2: calcd. C 70.65, H 4.55, N 2.75%; found: C 70.60, H 4.70, N 2.77%. Selected IR (KBr, cm-1): v(Cl-O) 1111. ESI-MS (positive): m/z 919 (M+). 1H NMR (300MHz, CDCl3): delta 8.83 (d, J=5.0Hz, 2H, phen H); 8.01 (s, 2H, phen H); 7.74 (d, J=5.0Hz, 2H, phen H); 7.62 (m, 6H, phenyl H); 7.57-7.51 (m, 4H, phenyl H); 7.37 (m, 6H, phenyl H); 7.26-7.14 (m, 24H, phenyl H). 31P{1H} NMR (162MHz, CDCl3): delta 2.97 (s, PPh3). UV/Vis (CH3CN): lambdamax /nm (epsilon/mol-1dm3cm-1): 228 (71180), 285 (58210), 381 sh (5810).
