Ferocenne
All reagents were provided by the Chemistry 108 laboratory and used without additional purification. All solvents were removed by rotary evaporation. All reaction products were isolated with vacuum filtration, unless otherwise stated. Infrared spectra were recorded on a Perkins-Elmer 1600 series FTIR Spectrometer using Nujol mulls and KBr pellets. 1H and 13C nuclear magnetic spectra were taken in CDCl3 at 300 MHz on an AMX Spectrometer. Ultra-violet-visible spectroscopy was performed using quartz cuvettes on a Hewlett-Packard 8452A Diode Array Spectrometer. All thin layer chromatography was performed in a / solvent system. In a 100mL round-bottom flask iron (II) chloride tetrahydrate (5g, mmol) was dissolved in nitrogen degassed DMSO (30mL) and stirred for 1h. The solution was stoppered to prevent oxidation. Diethyl ether (80mL) and flake K
20mL). The organic layer was poured into an evaporating dish and the ether was allowed to evaporate. After evaporation 0.59 g of orange crystals were afforded (%). A small sample of ferrocene was purified by sublimation. A 1H NMR, IR, and UV-Vis spectrum was obtained. Melting point: °C (lit. 174 °C). 1H NMR (ppm): 10 H, δ 4.17 (s); 13C NMR (ppm): δ ; (25°C, Nujol, cm-1): (), (), (), (), (), (), (), (), (), (); UV-Vis (25°C, , 1.000 cm, M): (λ=nm, ε=M), (), (), (), (). The solubility of ferrocene was tested in water, dichloromethane, and toluene. Ferrocene (0.1g, mmol) was added to water (5mL) followed by concentrated nitric acid (5mL). Ferrocene (1.0g, mmol) was added to acetic anhydride (3mL) in a 50mL round-bottom flask equipped with a calcium chloride drying tube. Phosphoric acid (0.7 mL) was added dropwise to this mixture with shaking. The mixture was heated on a steam bath for 20 minutes and then added onto cr
