Conclusions
-
1.
IR and PMR spectroscopy was used to study the different types of hydrogen bonds formed in solutions of β-hydrocarbonyl ferrocene compounds. The observed spectral behavior can be explained by the formation on an intramolecular hydrogen bond of the OH group with the iron atom only in the case of a dilute solution of the ethyl ester of 3-hydroy-2-(phenylferrocenylmethyl)-3-methylbutanoic acid.
-
2.
Only OH⋯OH− and OH⋯O=C interactions were found for this isomer in the crystalline state.
