Enthalpies of intramolecular interactions in ferrocenyl alcohols

Abstract

The ν_OH bands of a series of ferrocenyl alcohols and phenols have been studied as a function of temperature in carbon tetrachloride. From this, enthalpies have been calculated for the interaction of the hydroxyl group with both the ferrocenyl π-electrons and the d-orbitals of iron. The accessibility of the iron d-orbitals has been compared with those of the d-orbitals in the corresponding ruthenium and osmium compounds.
