Abstract: Acetylation of [5]ferrocenophane afforded the isomeric diacetyl[5]ferrocenophanes. The basically catalyzed reaction of 4-chlorobenzaldehyde or benzaldehyde with 3,4'-diacetyl[5]ferrocenophane (I) afforded, in addn. to condensation products, also derivs. of [5](1,1')[5](3,4')ferrocenophane-1,5-dione (e.g. II). The basically catalyzed cyclization of 3-acetyl-4'-(4-chlorocinnamoyl)[5]ferrocenophane furnished a doubly bridged deriv. of ferrocene.
