As a common heterocyclic compound, it belongs to iron-catalyst compound, name is Ferrocenecarboxaldehyde, and cas is 12093-10-6, its synthesis 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.

Iron(III) acetylacetonate, cas is 14024-18-1,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.

Monodispersed Fe3O4 nanoparticles having a mean diameter of 8 nm were synthesized following the seed-growth method described by Sun et al. (J. Am. Chem. Soc., 2004, 126, 273-279). To that end, 6 nm Fe3O4 seeds were synthesized by mixing Fe(acac)3 (2 mmol), 1,2-hexadecanediol (10 mmol), oleic acid (6 mmol), oleylamine (6 mmol), and benzyl ether (20 mL) under nitrogen flow. The mixture was heated at 200 C. for 2 hours and was then kept under reflux (300 C.) for 1 hour. The solution was cooled to room temperature and was then washed with methanol to remove the solvent and to finally be redispersed in hexane. The 6 nm nanoparticles to produce 8 nm nanoparticles were re-grown as indicated above and by adding 84 mg of 6 nm nanoparticles dispersed in hexane.
