I was reading a random text about the surface chemistry of YBaCuO superconductors. In the text, there was a table. The table had a list of several chemical compounds, including these two:

  • Alkyl Amine: FcC(O)NH(CH2)4NH2
  • Aryl Amine: p-Fc-C6H4-NH2

Two amines. After extensive search, I was unable to find a structural formula for it (the closest I've found was this). I even tried to draw all structural formulas I could think off in a piece of paper. But I couldn't draw a single one satisfying the second one (the easiest probably).

Can you identify these amines? What's their structural formula?

    $\begingroup$ @gilleain Its a good question. I have no idea what Fc means. I assume it most be something from coordination chemistry. In my searchs, I simply ignored the Fc- and the p-Fc-. $\endgroup$ Sep 13, 2016 at 19:52

    $\begingroup$ Fc = ferrocenyl; and p-Fc = para-ferrocenyl. $\endgroup$ Sep 13, 2016 at 21:30

The proposed strucutre of these compound are, correct me if i am wrong.

enter image description here


$\ce{Fc}$ stands for ferrocenyl.

So the first compound is an amide of ferrocenecarboxylic acid and tetramethylene diamine, and the second compound is p-ferrocenyl aniline.
