英文摘要	The reactions of cationic carbyne complexes of manganese and rhenium, [η-C^5H^5(CO)^2M≡CC^6H^5]BBr^4(1,M=Mn; 2, M=Re), with Na[η-C^5H^5Mo(CO)^3(3) in THF at low temperature afford η^1,η^2-ketene complexes [MnMo{C(CO)C^6H^5}(CO)^4(η-C^5H^5)^2] (8) and [ReMo{C(CO)-C^6H^5} (CO)^4(η-C^5H^5)^2] (9), respectively. Analogous reactions of Na[η-C^5H^5W(CO)^3] (4) with 1 and 2 give the corresponding ketene complexes [MnW{C(CO)C^6H^5(CO)^4(ηC^5H^5)^2] (10) and [ReW{{C(CO)C^6H^5}(CO)^4(η-C^5H^5)^2](11). Na[Co(CO)^3PPh^3(5) also reacts with 1 and 2 to yield ketenyl-bridged complexes [MnCo{C(CO)C^6H^5}(CO)^4(PPh^3)(η-C^5H^5)](12) and [ReCo{C(CO)-C^6H^5}(CO)^4(PPh^3)(η-C^5H^5)] (13), respectively. However,compound Na[η-C^5H^5Fe(CO)^2] (6) reacts only with 2 to form η~1,η~2-Ketene complex [ReFe{C(CO)C^6H^5}(CO)^3(η-C^5H^5)^2] (14), while the reactions of (Ph^3P)^2N[Fe(CO)^3NO] (7) with 1 and 2 produce dimetal bridging carbyne complexes [MnFe(η-CC^6H^5)(CO)^4(NO)](η-C^5H^5)] (15) and [ReFe(η-CC^6H^5)(CO)^4(NO)-(η-C^5H^5)] (16), respectively. Compound 15 treated with an excess of Fe^2(CO)^9 gives a trimetallic bridging carbyne complex, [MnFe^2(η^3-CC^6H^5)(CO)^7(NO)(η-C^5H^5)] (17). Complexes 12 and 13 also react with Fe^2(CO)^9, leading to loss of the PPH^3 ligand to afford trimetallic bridging carbyne complexes [MnFeCo(μ^3-CC^6H^5)(CO)^8(η-C^5H^5)] (18) and [ReFeCo(μ^3-CC^6H^5)-(CO)^8(η-C^5H^5)] (19), respectively. The structures of 10,13, and 15 have been established by X-ray diffraction studies.
