1271-55-2, Acetylferrocene is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

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.

Name is Iron(III) acetylacetonate, as a common heterocyclic compound, it belongs to iron-catalyst compound, and cas is 14024-18-1, its synthesis route is as follows.,14024-18-1

General procedure: A solvothermal method was implemented to prepare CuFe2O4and Fe3O4 NPs. For the synthesis of Fe3O4 NPs, 4 mmol of Fe(acac)3 and 40 ml of triethylene glycol were mixed in a 200 ml round bottom flask connected to a reflux condenser. To homogenize thesolution, the temperature was increased to 100 C and maintainedat this temperature for 1 h. Afterwards the obtained homogenoussolutionwas transferred to a Teflon lined autoclave (75 ml capacity)and then placed in a furnace at 260 C for 24 h. Next, the mixturewas left to cool down to room temperature, which resulted in a black homogeneous dispersion containing magnetite nanoparticles.The obtained product was washed with acetone severaltimes using centrifugation. Then, the nanoparticles were put to dryin an oven at 50 C for 12 h. For the synthesis of CuFe2O4 NPs, thesame procedure was employed except that the stoichiometricamount of Cu(acac)2 was added to the triethylene glycol at the firstof synthesis process. Briefly, the synthesis process is schematicallyshown in Fig. 1.

General procedure: In a 25-mL round-bottomed flask, a mixture of aryl iodide (5 mmol), alkene (6 mmol), and base (5.6 mmol) was placed in 4 mL of DMF, then a solution of the complex 3 (0.005 mol percent) in 1 mL of DMF was added. The reaction mixture was refluxed for the time stated in Tables 3 and 4 at 140 ¡ãC. The reaction mixture was poured into water (20 mL) and extracted with ether or hexane (2¡Á30 mL). The combined organic layers were dried over anhydrous sodium sulfate. After the removal of the solvent in vacuo, the resulting crude was purified by column chromatography on silica gel (hexane/ethyl acetate) to give the corresponding cross-coupling product (the purified product was identified by means of determination of mp and by 1H and 13C NMR, the data obtained are consistent with literature).26 The entire flasks used in the each coupling reaction were meticulously cleaned with aqua regia to avoid the presence of unseen palladium catalyst.
