The synthesis of iron (III) ethoxide revisited: Characterization of the metathesis products of iron (III) halides and sodium ethoxide

摘要

interaction of FeX3, X = Cl, Br with 3 equiv. of NaOEt in toluene/ethanol media provides mixtures of iron (III) oxoethoxide, Fe5O(OEt)(13), and its halide alkoxide analogs. The latter have been identified by mass-spectrometric study as Fe5O(OEt)(12)X and Fe5O(OEt)(11)X-2. Application of FeBr3 as a starting material leads to much more pure samples of Fe5O(OEt)(13) isolated with higher yields. (c) 2005 Elsevier B.V. All rights reserved.
