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
(Cmpd 12): 4,7-Diphenyl-2-(3-pyridyl)-1,10-phenanthroline. n-Butyllithium (18.8 ml of a 1.6 M solution in hexane, 0.03 mol) is added under argon to a cold (-78C) tetrahydrofurane (100 ml). 3-bromopyridine (4.75 g, 0.03 mol) is then added during 15 minutes while keeping the temperature at -78C. The brown solution is stirred 50 minutes at -78C, thereafter finely powdered 4,7-diphenyl-1,10-phenanthroline (6.64g, 0.02 mol) is added and the mixture is allowed to warm to room temperature during 40 minutes. Methanol (30 ml) is then added and the brown solution is evaporated on a rotary evaporator. The residue is dissolved in dichloromethane (300 ml) and methanol (10 ml), manganese dioxide (30 g) is added and the mixture is stirred at room temperature 12 h. The solids are removed by filtration, the filtrate is evaporated and the residue is crystallized from dichloromethane-ethanol and then o-dichlorobenzene to afford 2.1 g of the title compound. Light yellow, microcrystalline powder, mp (DSC in air, scan rate 10Cmin-1) = 268.3-273.5C. 1H-NMR (300 MHz, CD3Cl): 9.46 (d, J=1.8 Hz, 1H), 9.31 (d, J=4.5 Hz, 1H), 8.86 (d, J=11.7 Hz, 1H), 8.73 (d, J=6.6 Hz, 1H), 8.08 (s, 1H), 7.89 (s, 2H), 7.64-7.48 (m, 12H). MS for C29H19N3 (409.49) found M=409.69.
1662-01-7, 1662-01-7 4,7-Diphenyl-1,10-phenanthroline 72812, acatalyst-ligand compound, is more and more widely used in various fields.
