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

General procedure: For the sol-gel route, stoichiometric amounts of Fe(NO3)3¡¤9H2O, Mg(NO3)2¡¤6H2O and Mn(NO3)2¡¤4H2O were dissolved into 5 mL of C2H6O2 in a 100 mL beaker. This solution was stirred for 2 h at 40 C, and then the obtained sol was heated up to 80 C and kept at this temperature until a brown gel was formed. The gel was aged for 2 h at room temperature and then dried at 95 C for 72 h. Subsequently, the dried gel was heat treated at 400, 500 or 600 C in air for 30, 60, 90 or120 min. The obtained products were milled and then washed several times with ethanol, in order to remove the ethylene glycol excess. Finally, the powders were dried at room temperature. For the thermal decomposition method, stoichiometric amounts of the acetylacetonates of Fe, Mg and Mn, phenyl ether and oleic acid were placed in a threenecked flask of 250 mL. Subsequently, a thermometer was placed in one of the side necks and a reflux system was adapted. The solution was heated up to 250 C and it was maintained at this temperature for 30, 60 or 90 min. Once the reaction time passed, a precipitate was obtained, which was washed repeatedly with ethanol. Finally, the precipitate was dried at room temperature and milled. The characterization of the products was carried out by X-ray diffraction (XRD), vibrating sample magnetometry (VSM) and transmission electron microscopy (TEM).

The reaction mixture was stirred at that temperature during 24 h. The precipitated triethylamine hydrochloride was filtered off and washed with diethyl ether (5 ¡Á 10 mL). The filtrate was washed with 10 % aqueous NaCl and 5 % aqueous NaHCO3. The solvent was removed, and the residue was recrystallized from a benzene-hexane (2 : 1) mixture (14, 15, 19, and 20) or from hexane (16,17, 21, and 22). 3,4,4-Trichloro-1-cymantrenylbut-3-en-1-yl 4,5-dichloroisothiazole-3-carboxylate 18 was obtained as a viscous oil and was used without further purification.
