102-54-5, Ferrocene is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Ferrocenecarboxaldehyde was prepared from ferrocene according to the literature.10 Phosphorus oxychloride (50mL, 536mmol) was added dropwise to the dimethylformamide (39.0g, 536mmol) at 0C and the resulting mixture was stirred for 30min at this temperature under a nitrogen atmosphere. Next ferrocene (50.0g, 268mmol) in dry chloroform (250mL) was added dropwise to the mixture for 30min at 0C. After completion of the addition, the reaction mixture was kept stirring for 28h with heating at 55-60C on an oil bath, taking care that the temperature did not exceed 60C. The reaction mixture was then cooled to room temperature and neutralized carefully with an aqueous saturated Na2CO3 solution and then extracted repeatedly with the dichloromethane. The combined organic layer was dried over anhydrous Na2SO4, filtered and the solvent was evaporated under reduced pressure. The residue was purified through silica gel column chromatography using hexane/ ethyl acetate mixture (95:05) as eluent to give ferrocenecarboxaldehyde 1 in 55% yield (31.7g) as a reddish brown solid. (mp: 122C, lit.10 123C); IR (KBr, cm-1): 3093, 2837, 2760, 1683, 1447; 1H NMR (400MHz, CDCl3): deltaH 9.95 (s, 1H); 4.80-4.60 (m, 4H), 4.27 (s, 5H); 13C NMR (100MHz, CDCl3): deltaC 193.63, 79.49, 73.33, 69.78; HRMS-ESI (m/z): [M+H]+ Found 215.0157 and calculated 215.0159 for C11H11FeO.
The synthetic route of 102-54-5 has been constantly updated, and we look forward to future research findings.
