Abstract

The mixed-valent oxo-centered triiron(III, III, II) trifluoroacetate complex [(Fe2FeO)-Fe-III-O-II(C2CCF3)(6)(H2O)(3)] Was prepared by reacting anhydrous iron(III) chloride with boiling trifluoroaceric acid under nitrogen. The non-hygroscopic and readily available mixed-valent triiron trifluoroacetate complex Was found to be an efficient catalyst for the regioselective rearrangement of epoxides. A number of carbonyl compounds formed via the rearrangement of epoxides could be obtained by a simple filtration of the reaction mixture through a short plug of silica gel. (C) 2010 Elsevier Ltd.
