4733-39-5,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4733-39-5,2,9-Dimethyl-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 Ph2dmp (60.7mg, 0.18mmol) in MeCN (15ml) are stirred at room temperature for 1h. Slow evaporation of a MeCN solution of 4 afforded analytically pure complex as yellow crystalline solid. Yield (93.4mg, 62.9%). Elemental analysis for C62H50ClCuN2O4P2: calcd. C 71.06, H 4.81, N 2.67%; found: C 71.12, H 4.90, N 2.62%. Selected IR (KBr, cm-1): v(Cl-O) 1110. ESI-MS (positive): m/z 947 (M+). 1H NMR (300MHz, CDCl3): delta 7.98 (s, 2H, Phen H); 7.60 (m, 6H, phenyl H); 7.57-7.53 (m, 4H, phenyl H); 7.44 (s, 2H, phen H); 7.38-7.42 (m, 6H, phenyl H); 7.26-7.21 (m, 24H, phenyl H); 2.31 (s, 6H, -CH3). 31P{1H} NMR (162MHz, CDCl3): delta 0.87 (s, PPh3). UV/Vis (CH3CN): lambdamax/nm (epsilon/mol-1dm3cm-1): 228 (68830), 287 (53890), 369 sh (3950).
