Synthesis, structure, and properties of 1,1?-diamino- and 1,1?-diazidoferrocene

We report an improved synthesis of 1,1?-diaminoferrocene, employing the reduction of 1,1?-diazidoferrocene with H2-Pd/C, along with extensive characterization data for both compounds. Diaminoferrocene undergoes a reversible 1e- oxidation in CH3CN at a potential of -602 mV vs Fc0/+, one of the most negative redox potentials for a ferrocene derivative. The chemical reversibility of this process was confirmed by isolation of the stable, 17-electron [Fc(NH2)2]+ cation as PF6-, OTf-, and TCNE- salts. In the solid state, diaminoferrocene exists in two conformations: one with the NH2 groups eclipsed, and the other with the NH2 groups offset by one-fifth turn around the Cp-Fe-Cp axis. Diazidoferrocene, on the other hand, exhibits only the fully eclipsed conformation in the solid state. The Fe-Cp(centroid) vectors in the diazidoferrocene molecules are roughly aligned with the crystallographic c-axis, and the molecules form layers perpendicular to this axis. The compound is thermally unstable at elevated temperatures, and rapid heating above its melting point results in explosion.

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

Monodispersed Fe3O4 nanoparticles having a mean diameter of 8 nm were synthesized following the seed-growth method described by Sun et al. (J. Am. Chem. Soc., 2004, 126, 273-279). To that end, 6 nm Fe3O4 seeds were synthesized by mixing Fe(acac)3 (2 mmol), 1,2-hexadecanediol (10 mmol), oleic acid (6 mmol), oleylamine (6 mmol), and benzyl ether (20 mL) under nitrogen flow. The mixture was heated at 200 C. for 2 hours and was then kept under reflux (300 C.) for 1 hour. The solution was cooled to room temperature and was then washed with methanol to remove the solvent and to finally be redispersed in hexane. The 6 nm nanoparticles to produce 8 nm nanoparticles were re-grown as indicated above and by adding 84 mg of 6 nm nanoparticles dispersed in hexane.

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

Nanosized Fe2O3 was synthesized by the thermolysisof an iron-containing precursor in a dispersion medium. Iron acetylacetonate prepared as describedin [7] was used as a precursor; the dispersion medium was diphenyl ether (DPE). The choice of DPE wasbased on the thermal stability, high boiling point (259C), and low toxicity of this material. Iron acetylacetonate(0.5 g) was dissolved in 10 mL of DPE;40 mL of DPE in a two-necked round-bottom flaske quipped with a reflux condenser was heated in an oil bath to 200C under vigorous stirring with a magnetic stirrer. After that, using a syringe, the iron acetylacetonate solution was rapidly introduced into hot DPE. The resulting mixture was held under vigorous stirring for 2 h to provide the completion of thermolysis and the formation of iron oxide particles; after that, the mixture was cooled and analyzed. To study the features of reduction of Fe2O3 and the chemisorption processes involving it, DPE was removed by vacuum distillation; the resulting material was a black powder.

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

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.
