Abstract
The (µ3-acetyl)-nonacarbonyltriferrate(1–) ion, [Fe3(CO)9(µ3-MeCO)]–, reacts with fluoroboric acid to give the neutral clusters Fe3(CO)9(µ3-MeCO)(µ-H)(1), Fe3(CO)10(µ-CMe)(µ-H)(2), and in small yield, Fe3(CO)9(µ3-MeCOH)(3). With methyl fluorosulphate the anion reacts to give either Fe3(CO)9(µ3-CMe)(µ3-OMe)(4) or Fe3(CO)9(µ3-CMe)(µ3-COMe)(5), depending upon the reaction conditions. The crystal structures of (1), (4), and (5) have been determined by X-ray diffraction studies. Mechanisms for the electrophilic attacks and for the C–O bond cleavage of the µ3-acetyl group are discussed.Keywords
