To prepare nanosized iron(III) oxide, 0.5 g ofFe(acac)3 was dissolved in 10 mL of DPE or a mixture of DPE with the appropriate amount of surfactant.Next, 40 mL of DPE or a DPE-surfactant mixture was heated to required temperature on an oil bath withvigorous magnetic stirring in a two-necked round-bottomed flask equipped with a reflux condenser. Next, a solution of Fe(acac)3 was quickly added via a syringe into the hot DPE or DPE-surfactant solution. The resultant mixture was kept for 2 h with vigorous stirring for complete thermolysis and formation of nanosized particles. Then, the mixture was cooled and analyzed.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1271-42-7,Ferrocenecarboxylic acid,as a common compound, the synthetic route is as follows.

Ferrocene (6.0 g, 32 mmol) and potassium tert-butoxide (0.46 g, 4.08 mmol) were completely dissolved in dry THF (300 mL). The orange solution was cooled to -78 0C when tertbutyllithium (34.0 mL, 64.5 mmol, 1 .9 M in pentane) was added dropwise over a period of 15 mm, with the temperature maintained below -70 00. The reaction mixture was stirred at -78Cfor 1 h and then poured on a slurry of dry ice (excess) and diethyl ether. The mixture was warmed to room temperature overnight and extracted with an aqueous solution of sodium hydroxide (0.75 N, 4 x 250 mL). The combined aqueous layers were neutralized with hydrochloric acid (pH > 4) and the resulting orange solid was extracted with Et20 (4 x 250 mL) until the organic layer remained colourless. The combined organic layers were filtered toremove traces of ferrocenedicarboxylic acid, dried over MgSO4, filtered and the solvent wasevaporated under reduced pressure to give ferrocenecarboxylic acidas an orange solid in35% yield. After suspending the ferrocenecarboxylic acid (462 mg, 2.01 mmol) in dry CH2CI2(23 mL), oxalyl chloride (1100 iL, 13.64 mmol) in dry CH2CI2 (10 mL) was added dropwise tothe reaction mixture whereby the orange suspension turned dark red. The reaction mixturewas refluxed for 2 h and then stirred overnight at room temperature. The solvent was thenremoved under vacuum. The product was not purified and used immediately for the next synthetic step.

Nanoparticles narrow diameter distribution were prepared by the high-temperature decompositionof Co(acac)2 and Fe(acac)3 with the 1:2 Mratio (0.6:1.2mmol) together with 1-2 octanediol, diphenyl ether (boiling point at 550 K)and oleic acid and oley-lamina as surfactants. The particle size was tailored by the sur-factant: precursor molar ratio ([Surf.]:[Prec.])according to there-ference [15]. The preparation was magnetically stirred and heated up to the boiling temperature T535 K for 120 min. After synthesis the nanoparticles were extracted by adding ethanol followed by centrifugation(14,000rpm/30min). After that,they were washed with acetone and centrifuged once again. The final sample consists in a black powder constituted by cobalt ferrite nanoparticles covered with an oleic acid layer, which is strongly linked to the surface, improving the chemical stability, and avoiding agglomeration. The samples were labeled S2,S5,and S7 with mean diameter 2.0,4.5,and 7.0 nm respectively, obtained from the TEM analysis.

1271-51-8, Vinylferrocene is a iron-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

About 424 mg (about 2 mmol) of vinylferrocene, about 312 mg (about 0.5 mmol) of tris(4-iodophenyl)amine and about 7 mg (about 6 mol percent) of palladium acetate were placed in a flask. After a reflux condenser was connected to the flask, about 3 ml of 1,4-dioxene as a solvent, about 480 mul (about 2 mmol) of tri-n-butylamine as a base and about 11 mul (about 9 mol percent) of tri-t-butylphosphine were injected into the flask using a syringe under a nitrogen atmosphere. The solution was degassed with nitrogen gas, and refluxed in an oil bath. The reaction was allowed to proceed for about 4 days. The reaction solution was diluted with about 10 ml of methylene chloride and neutralized with a saturated aqueous solution of ammonium chloride. The neutralized solution was transferred to a separatory funnel, followed by phase separation. The obtained organic layer was dried over anhydrous magnesium sulfate and passed through a glass filter to obtain a transparent polymer solution. The polymer solution was evaporated under reduced pressure to remove the solvents. The residue was purified by column chromatography using toluene/hexane (1/2), yielding the metallocenyl dendrimer (about 301 mg) of Formula 2 as an orange solid. The 1H-NMR spectrum of the metallocenyl dendrimer is shown in FIG. 3., 1271-51-8

The magnetic nanoparticles were synthesized according to a previously reported procedure26. Briefly, a solution of Fe(acac)3 (5.65 g, 0.016 mol), benzyl ether (80 mL) and oleylamine (80 mL) was heated to 110 C and allowed to reflux for 1 h with vigorous stirring. The temperature was raised to 210 C and then refluxed for 2 h under an argon atmosphere. After cooling to room temperature, the reaction mixture was centrifuged at 10,000 rpm for 20 min, affording the magnetic nanoparticles (Fe3O4) as a black solid. The magnetic nanoparticles were then dispersed in a mixture of 1-propanol (180 mL), conc. NH4OH (25 mL) and deionized water (18 mL) in a 500 mL round-bottom flask by ultra-sonication for 30 min under an argon atmosphere. Following this, tetraethylorthosilicate (TEOS) (6 mL, 0.027 mol) was added dropwise for 30 min with vigorous stirring. After stirring at room temperature for 6 h, thesilica-coated magnetic nanoparticles (Fe3O4(at)SiO2) were separated from the solution using an external magnet and then washed twice successively with 1-propanol and deionized water, respectively. The Fe3O4(at)SiO2 nanoparticles (brown solid) were then dried under vacuum at 60 C for 6 h, prior to use.
