14024-18-1, Iron(III) acetylacetonate is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Cobalt (II) acetylacetonate Co(acac)2 and Iron (III) acetylacetonateFe(acac)3 precursors weighted as 1:2M ratio was dissolved in 50 ml of de-ionized water. The aqua solution was kept warm at 40 C for few minutes and very few drops of inorganic chemical reagent was added dropwise and stirred for 30 min to mix the cations homogeneously throughout the solution. 1% of alkali solution was added dropwise to the aqua precursor solution for a better control of particle size, which acts as a precipitating agent as well as maintaining the pressure in the autoclave by lowering the equilibrium vapour tension of water. Finally,the precursors solution was continuously stirred for 30 min and transferred into 150 ml Teflon coated stainless steel autoclave. Then the autoclave was sealed and kept in the muffle furnace for heat treatmentat the optimised reaction temperature of 200 C for 6 h and allowed to cool down to room temperature. The obtained dark precipitation was filtered by Whatman filter paper and washed several times by de-ionized water and absolute ethanol. The precipitate was then dried at 80 C for 5 h in hot air oven and subsequently annealed at 700 and 800 C. The samples were named as S1 (as-prepared),S2 (annealed at 700 C), and S3 (annealed at 800 C).

14024-18-1, 14024-18-1 Iron(III) acetylacetonate 91759530, airon-catalyst compound, is more and more widely used in various fields.

Iron Catalysis in Organic Synthesis: A Critical Assessment of What It Takes To Make This Base Metal a Multitasking Champion

Vinylferrocene, cas is 1271-51-8, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.,1271-51-8

About 424 mg (about 2 mmol) of vinylferrocene, about 312 mg (about 0.5 mmol) of tris(4-iodophenyl)amine and about 7 mg (about 6 mol percent) of palladium acetate were placed in a flask. After a reflux condenser was connected to the flask, about 3 ml of 1,4-dioxene as a solvent, about 480 mul (about 2 mmol) of tri-n-butylamine as a base and about 11 mul (about 9 mol percent) of tri-t-butylphosphine were injected into the flask using a syringe under a nitrogen atmosphere. The solution was degassed with nitrogen gas, and refluxed in an oil bath. The reaction was allowed to proceed for about 4 days. The reaction solution was diluted with about 10 ml of methylene chloride and neutralized with a saturated aqueous solution of ammonium chloride. The neutralized solution was transferred to a separatory funnel, followed by phase separation. The obtained organic layer was dried over anhydrous magnesium sulfate and passed through a glass filter to obtain a transparent polymer solution. The polymer solution was evaporated under reduced pressure to remove the solvents. The residue was purified by column chromatography using toluene/hexane (1/2), yielding the metallocenyl dendrimer (about 301 mg) of Formula 2 as an orange solid. The 1H-NMR spectrum of the metallocenyl dendrimer is shown in FIG. 3.

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.

General procedure: As shown as the synthetic protocol A in Scheme 2, compounds 1-11 were synthesized following literature description [16] with m-methoxyphenol, p-methoxyphenol, resorcinol, and hydroquinone as reagents. One hydroxyl group in resorcinol and hydroquinone was protected by tert-butyldimethylsilyl chloride.

The mixture was diluted with CH2Cl2 and washed by saturated NaHCO3 and water. The organic phase was dried over anhydrous Na2SO4, and the solvent was removed under vacuum. The residue was purified by column chromatography with CH2Cl2 as the eluent to afford thiophthalimides as colorless solid. The following cycloaddition reactions were carried out in dry CHCl3 solution of thiophthalimides (~ 0.1 M) and styrenes (2 equiv.) or vinyl ferrocene (2 equiv.) and freshly distilled (C2H5)3N (2 equiv.) at 60 ¡ãC. The reaction was finished with thiophthalimides not detected by TLC. Then, the solvent was evaporated under vacuum pressure, and the residual solid was purified with column chromatography to afford silylated adducts. The desilylation operation was performed in dry tetrahydrofuran (THF) solution containing 0.04 M aforementioned adducts at 0 ¡ãC, to which a solution of (n-C4H9)4NF*3H2O in THF (1 equiv. for each protective group) was added. The reaction was finished with the reagent not detected by TLC, and then the mixture was diluted with ethyl acetate and washed with saturated NH4Cl and water.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-55-2,Acetylferrocene,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.
