0.92 g (80%) | With sodium hydroxide; In tetrahydrofuran; water; propionic acid; | 2,9-bis(4-formylphenyl)-1,10-phenanthroline (4). Compound (3) (2.00 g, 2.96 mmol) and powdered NaOH (0.71 g, 17.7 mmol) were refluxed in propionic acid (15 mL) for 6 h under argon. The propionic acid was evaporated under reduced pressure and replaced with THF (25 mL) and 2M NaOH (5 mL). The solution was stirred for 1 h, and then the THF was evaporated. Water (20 mL) was added and the pH adjusted to ~8 with HCl. The solution was extracted with CH2 Cl2 (3*100 mL). Yield 0.92 g (80%). 1 H NMR (CDCl3) δ8.38 (s, 2H), 8.64 (d, J=8.4 Hz, 4H), 8.42 (d, J=8.4 Hz, 2H), 8.25 (d, J=8.4 Hz, 2H), 8.13 (d, J=8.4 Hz, 4H), 7.89 (s, 2H). |

84% | With hydrogenchloride; water; In tetrahydrofuran; at 20℃; for 48h; | Synthesis of 4,4'-(1,10-phenanthroline-2,9-diyl)dibenzaldehyde (4; Scheme I) A 5% HCl aqueous solution (36 mL) was added to a stirring solution of 3 (900 mg, 1.61 mmol) in tetrahydrofuran (180 mL). The mixture was stirred at ambient temperature for 48 h, and then the solvent was evaporated in vacuo. The residue was suspended in a saturated NaHCO3 aqueous solution (100 mL) and DCM (100 mL). The organic layer was collected and dried over MgSO4. The solvent was removed by evaporation and resulting crude product was purified by column chromatography using DCM. |
