“…[14] Cp*Fe(CO)2Cl (Fp*Cl) was synthesised according to a published procedure. [15] Toluene, pentane and chloroform were dried using an Innovative Technology Pure Solv SPS-400; diethyl ether and THF were distilled from purple Na/benzophenone diketyl. Toluene, pentane and diethyl ether were stored over a K mirror; chloroform and THF were stored over 4 Å molecular sieves.…”

“…Reaction vessels were oven‐dried at 150 °C and solvents were freshly distilled using the appropriate drying agent prior to use. Fe(CO) 5 and dicyclopentadiene were purchased from Aladdin and used as received to prepare [{CpFe(μ‐CO)(CO)} 2 ] by following the previously reported procedure 20. Complexes 1 – 3 were synthesised by following the procedures described previously with some modifications when necessary 15.…”

“…[(η 5 ‐C 5 H 5 )Fe( cis ‐CO) 2 Cl] ( 1 ): Concentrated HCl (12 mol L −1 , 5 mL) was added to a solution of [{CpFe(μ‐CO)(CO)} 2 ] 20 (0.5 g, 1.4 mmol) in ethanol (30 mL). After being stirred overnight, the solvent was removed under reduced pressure to produce a residue that was purified with column chromatography (eluent: ethyl acetate/petroleum ether 1:4) to produce a red solid (yield: 234 mg, 1.1 mmol, 40 %).…”

“…Em concordância com o caráter de dupla ligação, a frequência vibracional de grupos CO "cetônicos" (ponte simples) cai para valores situados entre 1750-1850 cm -1 . 20,21 No espectro na região do infravermelho do composto eneacarboniladiferro sintetizado (Figura 4) é possível observar uma banda em 1824 cm -1 referente ao CO ligado em ponte e mais duas bandas em 2015 e 2085 cm -1 referente aos estiramentos simétricos e assimétricos, respectivamente, do CO terminal. Tais bandas estão de acordo com o apresentado na literatura.…”
