The reaction mixture was warmed to room temperature and stirred for 16h. A solution of NaBH4 (2.38g, 63mmol) in 25ml diglyme was added dropwise to the purple reaction mixture at-5C. An orange solution was formed and stirred at 0C for 1h. The mixture was then hydrolyzed with addition of 20ml water while maintaining its temperature at less than or equal to 10C. The mixture was allowed to separate by settling and the organic phase was then withdrawn. The aqueous phase was extracted with 3 times 30ml of dichloromethane and then all the organic phases are combined. Combined organic layer was washed with 50ml of brine and then dichloromethane was distilled under atmospheric pressure. The diglyme and the residual ferrocene which was found to be entrained by the diglyme were then distilled at reduced pressure approximately 20mm Hg and a column head temperature of 85-95C. The alkylferrocene derivatives were distilled at a more reduced pressure, less than 5mm Hg.

12093-10-6, Ferrocenecarboxaldehyde is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,12093-10-6

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.
