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

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.

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.

14024-18-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Iron(III) acetylacetonate, cas is 14024-18-1,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.

Fe(acac)3 (3 mmol) was dissolved in 20 ml of oleylamine and 5 ml of n-hexane. The reaction mixture was thoroughly stirred under N2 atmosphere for 30 min in a 50 ml Teflon-lined stainless steel autoclave that was carefully sealed. The autoclave was heated in a furnace at 190 C for 8 h under autogenous pressure. The resulting dark suspensions were extracted by adding 50 ml of ethanol followed by centrifugation. After washing the precipitates three times with ethanol, uniform Fe3O4 NPs were formed. These NPs were redispersed into n-hexane and a black-brown n-hexane dispersion of Fe3O4 NPs was thus obtained. Thus, the Fe3O4 suspension was transferred to 100 ml volumetric flask, evenly mixed with n-hexane for measurement of concentration of Fe3O4 through the 1,10-phenanthroline monohydrate dyeing method using UV-Vis spectrophotometer. Similar procedures for the preparation of Fe3O4 NPs were carried out at different conditions, including different reaction temperatures, times, and solvents. The solvothermal temperatures for samples S1 and S3 differed from that for S2. For samples S4-S6, the reaction times differed from that of S2. For samples S7-S9, the content of n-hexane differed from that of sample S2. The detailed preparation conditions are listed in Table 1 .

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 Iron(III) acetylacetonate, 14024-18-1
