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

14024-18-1, In the next few decades, the world population will flourish.

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

Fe3O4 nanoparticles were prepared by the following synthetic procedure, which was based on our previous study [29]: the reaction was carried out in the 100 mL three-necked round-bottom flask equipped with a condenser and a thermometer. The heating was carried out by a heating mantle. Iron acetylacetonate (III) (1 mmol) and 1,2-hexadecanediol (3.0 mmol) as Fe3+ reducing agent were added into a mixture of oleic acid (15 mmol) and distilled oleylamine (15 mmol). The solution was maintained at 130 C for 30 min with vigorous stirring under a reduced atmosphere (ca. 200 Pa) for dissolution and removal of impurities such as water molecules and organic molecules with low boiling temperatures. In this phase, the solution color was dark brown. Then, the solution was heated to reaction temperatures of 200 C, 250 C, 280 C, and 300 C for 1 h, 3 h, and 6 h under a nitrogen atmosphere (1 atm.). The solution color changed to black. Finally, the solution was left to cool to room temperature by remove of the heat source. When the solution becomes hard or loses fluidity after cooling to room temperature, the resulting solidified solution was dissolved by adding 10 mL n-hexane before the following precipitation process. The iron oxide nanoparticles were precipitated by the addition of ethanol (70~80 mL) and were subsequently subjected to centrifugation (3000 g, 10 min).The precipitated nanoparticles were redispersed into n-hexane.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 14024-18-1, Iron(III) acetylacetonate

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

General procedure: Monodisperse synthetic Fe1-xMgxFe2O4 (x=0, 0.1, 0.2, 0.3, 0.4, & 0.5) nanospheres were synthesized by recently developed solvothermal reflux method using high boiling point organic solvents mixture as reaction solvent [14,15]. Iron(III) acetylacetonate or Fe(C5H7O2)3 (solid, 97 %, Sigma-Aldrich), Magnesium acetylacetonate or Mg(C5H7O2)2 (solid, 97 %, Aldrich) were used as metal precursors. Benzyl ether (liquid, 98 %, Aldrich, boiling point (bp): 298C) and oleylamine (liquid, 70 %, Aldrich, bp: 364C) solvents mixture as reaction solvent, and oleic acid (liquid, 65 %, SDFCL, bp: 360C) as surfactant were used. To synthesize 0.5g of target composition compound, 40mL of benzylether (BE) and 10mL of oleylamine (OAm) solvents mixture were taken as reaction solvent in three neck round bottom (RB) flask (250mL). The mixture was stirred with magnetic stirrer for 10min. to make it homogeneous. Metal precursor powders were finely grounded to enhance their decomposition. Stoichiometric metal precursor fine powders were added to the reaction solvents mixture. The mixture was stirred for 10min. to make homogeneous solution. Then 5mL of oleic acid (OA) (?2.5 times of metal cations mols) was added. The resultant reactants mixture was heated to boiling point of the solvent mixture (300C) by electric heating mantle at 5C/min ramp. The boiling solvents produce natural gas bubbles. The reaction was carried out for 1h at this temperature and then naturally cooled the RB flask to room temperature. To precipitate crystallined ferrite nanoparticles, anti-solvent such as ethanol was added to the reaction mixture. The precipitated nanoparticles were separated by sedimentation principle through centrifugation. The nanoparticles were redispersed in good solvents such as n-hexane. To further purify the nanoparticles from residual organic molecules (surfactant), the redispersed particles were precipitated, separated and redispersed by the above procedure, at least two times.
