YieldReaction ConditionsOperation in experiment
91% With hydrogen bromide; dihydrogen peroxide In methanol; water at 20℃; for 20 h; A stirred solution of terpyridine (3.0 g, 0.013 mmol) and HBr (1.04 g, 0.7 mL, 0.013 mmol) in CH3OH (60 mL) was added to a 47percent aqueous solution of H2O2 (0.44 g, 0.4 mL, 0.013 mmol) slowly, over a period of 15 min at room temperature. The mixture was stirred for 20 h whilst monitoring the reaction progress by TLC. After completion, the solvent was removed under reduced pressure and the residue dissolved in EtOAc (150 mL), washed with brine (3 .x. 100 mL) and dried over anhydrous Na2SO4. The product was isolated by careful column chromatography on silica gel using CH2Cl2-EtOAc (4:1, v/v, 200 mL) to give a yellow-red viscous liquid which was allowed to air dry, and finally recrystallized from Et2O-EtOH to afford the title compound 1 (2.74 g, 91percent) as a bright yellow solid.
