With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.12093-10-6,Ferrocenecarboxaldehyde,as a common compound, the synthetic route is as follows.

General procedure: To a suspension of methyltriphenylphosphonium bromide (1equiv.) in dry THF (100 mL), under nitrogen atmosphere at room temperaturewas added potassium tert-butoxide (7.0 equiv.). The solutionwas stirred for 1 h and then a solution of the aldehyde (1 equiv.) indry THF (30 mL) was added slowly. The mixture was stirred at roomtemperature for 12 h andwas evaporated to dryness. The unreacted potassiumtert-butoxide was quenched with saturated NH4Cl solution(10 mL). The reaction mixture was then extracted with CHCl3(200 mL), washed with water (2 ¡Á 200 mL), brine (100 mL) and then dried over anhydrous Na2SO4. Evaporation of the organic layer gave aresidue, which was purified by column chromatography using hexaneas the eluting solvent to give the corresponding vinyl compounds.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.12093-10-6,Ferrocenecarboxaldehyde,as a common compound, the synthetic route is as follows.

General procedure: The substituted ketone (3 mmol) and KOH(0.2 g) were dissolved in ethanol (5 mL) in a round bottomedflask and stirred at room temperature (25 C) for 10 min. Anethanolic solution of the substituted aromatic aldehyde (3 mmol,5 mL) was added drop wise and the mixture was stirred at roomtemperature. The progress of the reaction was monitored by TLCon silica gel sheets. The reaction was stopped by neutralizingthe stirred solution with 2 M HCl. In most of the cases the productwas obtained as a dark red precipitate after neutralization. It wasthen removed by filtration, washed with water. In the absence ofa precipitate on neutralization, the solution was extracted withethyl acetate (20 mL ¡Á 3). The organic layer was dried overanhydrous sodium sulphate and removed by evaporation underreduced pressure to give a liquid residue. The latter was passedthrough a column of silica gel (230-400 mesh) and eluted withTHF-hexane (1:4) to yield pure compound. All the synthesizedcompounds were well characterized by spectroscopic methodssuch as IR, NMR, Mass and elemental analysis and their spectralcharacteristics were found to be in good general agreement withthose found in literature30.

12093-10-6 Ferrocenecarboxaldehyde 11138449, airon-catalyst compound, is more and more widely used in various.

Example 2: Synthesis of ferrocenyl chalcones 1 a-f General preparation of ferrocenyl chalcones: Ferrocene carboxaldehyde (1 eq) and the appropriate 2-hydroxyacetophenone (1 eq) were dissolved in absolute ethanol (40 mL) in a 100 mL two necked round bottom flask. After stirring the mixture 10 to 15 min. at room temperature, sodium hydroxide (3 eq) was added, and the solution was stirred overnight. The mixture was poured into water (100 mL) and hydrochloric acid (12 M, 15 mL), extracted with dichloromethane (3 x 50 mL), and washed with water. The organic phase was dried over magnesium sulfate, filtered, and the solvent removed by evaporation. The product was purified by silica gel chromatography, using a mixture of petroleum ether/dichloromethane 4:1 as an eluent, and again using HPLC in acetonitrile/water (90:10). After HPLC purification, the acetonitrile was removed under reduced pressure and the aqueous phase extracted with dichloromethane.
