Abstract

The alkynyl ketone [Ru(CCCOCHMe₂)-(PPh₃)₂(Cp)] (1) reacts with trifluoroacetic anhydride at ambient temperature to give [Ru{CCC(OCOCF₃)CMe₂}(PPh₃)₂(Cp)]·0.5Et₂O (2), an enynyl trifluoroacetate ester which structurally resembles a ruthenium butatrienylidene cation ([RuCCCCR₂]⁺) trapped by the attachment of a trifluoroacetate anion to C_γ. Compound 1 also reacts with 2 equiv of trifluoroacetic anhydride to form [Ru{CC(COCF₃)C(OCOCF₃)CMe₂}(PPh₃)₂(Cp)] [H(CF₃CO₂)₂] (3), in which C_β of compound 2 has been acylated by a trifluoroacetyl group. The structures of 2 and 3 have been determined by X-ray crystallography.
