CAS# 1273-94-5
Ferrocenes are compounds containing an iron ion sandwiched between two five-membered carbon rings. Their chemistry involves overlap of the ns, np and eta orbitals in the ring structure with molecular orbitals of appropriate symmetry in the ion.
The ion in a metallocene can be acylated by alkyne-mediated reactions and by Friedel-Crafts double acylation. This reaction is especially effective on a ferrocene with a single oxidatively cleaved ring. The resulting compound is an organoferrocene with an eta-5 bonding between the rings and the Fe2+ ion.
