摘要：

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=CR27+) trapped by the attachment of a trifluoroacetate anion to C(gamma). Compound 1 also reacts with 2 equiv of trifluoroacetic anhydride to form [Ru{C=C(COCF3)C(OCOCF3)CMe2}(PPh3)2(CP)][H(CF3CO2)27 (3), in which C(beta) of compound 2 has been acylated by a trifluoroacetyl group. The structures of 2 and 3 have been determined by X-ray crystallography.
