Abstract: 3-(Ferrocenylcarbonyl)bicyclo[2,2,l]hept-5-ene-2-carboxylic acid and el­even derivatives of titanium bis(cyclopentadienyl)ferrocenecarboxylate (( η-C₅H₅)₂TiX_2-nY_n: X = CI, n = 1 or 2, Y = ferrocenylcarbonyloxy, 2-fer- rocenylacetoxy, 3-ferrocenyl-3-oxopropanoyloxy, 4-ferrocenyl-4-oxobuta- noyloxy, 4-ferrocenylbutanoyloxy, and 3-(ferrocenylcarbonyl)bicyclo[2,2,l]- hept-5-ene-2-cafbonyloxy; X and Y = 4,4,-ferrocenyl-4,4,-dioxodibuta- noyloxy) have been synthesized and their IR, ¹H NMR, and UV spectra are discussed. It is shown that these carboxyl groups are monodentate ligands in the mentioned titanium complexes.
