General procedure: A solution of pure TsNHNH2 (15 mmol) in methanol (30 mL) was stirred and heated to 60 C until the TsNHNH2 dissolved. The mixture was cooled to room temperature. Then a solution of ferrocenylketone (10 mmol) in methanol was dropped into the mixture slowly. After approximately 0.5-2 h, the crude products could be obtained as solid precipitate. The precipitate was washed with petroleum ether then removed in vacuo to give the pure products. In general, the yields were 68-86 %. Because of the relatively low activity of some ketones, their reactions at room temperature may be incomplete. They should be reacted in refluxing methanol. The reaction could be monitored by TLC.

With the synthetic route has been constantly updated, we look forward to future research findings about Acetylferrocene,belong iron-catalyst compound

The combined organic layers were filtered to removetraces of ferrocenedicarboxylic acid, dried over MgSO4, filtered and the solvent was evaporated under reduced pressureto give ferrocenecarboxylic acidas an orange solid in 35% yield. After suspending the ferrocenecarboxylic acid (462 mg,2.01 mmol) in dry CH2Cl2 (23 mL), oxalyl chloride (1100 mL, 13.64 mmol) in dry CH2Cl2 (10 mL) was added dropwiseto the reaction mixture whereby the orange suspension turned dark red.

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.,14024-18-1

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.

With the complex challenges of chemical substances, we look forward to future research findings about Iron(III) acetylacetonate

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.14024-18-1,Iron(III) acetylacetonate,as a common compound, the synthetic route is as follows.

A typical procedure for preparation of oil-soluble magnetite nanoparticles is briefly described as follows: first, 20 mL of diethylene glycol, 0.70 g (2 mmol) of iron (III) acetylacetonate, and 1.06 mL (3 mmol) of oleic acid were mixed in a 50 mL Teflon-lined stainless autoclave while magnetically stirring. Then, the autoclave was put into oven, kept at 180C for 5 h. After cooled to room temperature naturally, 40 mL ethanol was added to yield a black precipitate. The black Fe3O4 precipitate was separated by centrifuging at 10,000 rpm for 20 min, and re-dispersed in 10 mL of hexane or dried at 60C under vacuum for 24 h. (The as-prepared product was donated as SO1.) The as-synthesized Fe3O4 colloid in hexane is hydrophobic and stable for nearly a year, while the dried Fe3O4 sample can be stable for several months. The synthesis of water-soluble magnetite nanoparticles was carried out only by reacting an iron precursor, iron (III) acetylacetonate (Fe(acac)3), in the polyol medium (diethylene glycol) without oleic acid under the same reaction conditions. After cooling down to room temperature, 40 mL of ethyl acetate was added to the reaction solution resulted in a black precipitation of magnetite nanoparticles which was then separated from the solution by centrifuging at 10,000 rpm for 20 min. After washed with ethyl acetate for three times, the precipitation was re-dispersed in polar solvents such as ethanol and water for further investigation. The Fe3O4 solid productions could also be obtained by drying the precipitation at 60C under vacuum for 24 h. (The as-prepared product was donated as SW1.)
