Colorful fractions just after a column chromatographic purification of a ferrocene derivative.
Ferrocene is an organometallic compound with the formula Fe(C5H5)2. It is a metallocene, a type of organometallic chemical compound consisting of two cyclopentadienyl rings bound on opposite sides of a central metal atom, it’s a sandwich compound.
Depending on the substitution pattern, the compounds containing a ferrocene ring could vary in really different colors often between yellow and blood red.
In this case I needed to get rid of an oxidized compound what also formed from my reaction, this is in the first two-three test tubes and my target compound what has an intense orange color was in the last collected fractions.
