Sodium cyclopentadienide?

Explanation:

C5H7Br+NaOEtC5H6+NaBr+EtOH

C5H6+NaOEt[C5H5]Na++EtOH

1 equiv gives the diene, C5H6; the 2nd equiv gives cyclopentadienyl anion. These days, in inorganic laboratories, you can prepare 100g quantities of base-free NaCp simply by boiling up sodium metal with dicyclopentadiene, C10H12,
